Measurements diapearing from Garmin Connect

Having this issue too. My weight uploads but is then overwritten by an old weight. I've uninstalled gc and 're setup all devices. I've noted the following
-under users settings in gc there is a weight field that the user manuallypopulates when setting up the account. Thid is the same value that continually overwrites my scales data.
- The value in this field is "stuck". Even if I change it it reverts back to the same weight
-when I weigh myself the index scales uploads and the main screens on gc update. I get all the values on my home page and on the health stats - weight field. The weight field under user settings does not uodate
-when my garmin fitness tracker (fenix) syncs the weight recorded from my index scales to health stats - weight is overwritten by the value in user settings - weight field
- even if I don't record my weight on a given date gc will contain a calender icon stating that I did record one. On these dates the weight recorded is the incorrect value stored in user settings - weight

Hi,
besides the annoying WiFi connection issue, I'm now facing the "data disappearing" bug, too.

When I weigh myself and the check-mark shows up that the data has been synced, the data points are shown in GC.
But after a few minutes, only the weight data (and BMI which is just calculated) remains, the rest of the data are gone... just disappeared.

I have tried the setup with and without MFP connection. Same issue.
I'm using a fenix 5 constantly... so my guess is that as soon as fenix puts data into GC, the scale data is lost (but that's just a guess...).

The thing is: I've been using the exact same setup for years and it worked. All of a sudden now, this data issue now came up.

Garmin, pls look into and fix this!!

Me: All data was shown at first but after a few minutes it disappeared. Only shown on daily overview.
Wife: Not using any other Garmin product or even the app, the data is still there.

Am experiencing the same issue.. since last friday. Fenix 5 was updated to latest version and received 2 new versions of GCM for Android in the meantime as well. All weight data is present after weighing in both GCM and web page. Even after an activity (recorded with the Fenix) everything is still there. Just noticed that my "extra" data disappears around 12.00hrs (GMT+1).

Had a similar issue some time ago, but then all (extra) data was cleared when I synced an activity. That problem was solved by removing the link to MyFitnessPal. Just noticed that although both apps are no longer linked on the Garmin Connect web page (account settings) for whatever reason they were linked in GCM. Just removed that coupling as well...Now wait until tomorrow and see what happens around noon.

update:
1) this morning I weigh myself
2) check garmin connect and verify that the data are present
3) start a registration, save it
4) synchronize the fenix 5 with connect 4.2.2
5) check the data of fat mass, water etc.
6) surprise, the data disappeared

I repeat:
I do not use myfitnesspall
I do not use apple health
all disconnected on iphone and mac.

Garmin, it will be possible that you do not read this trend
Wake up we did 50 free tests

Garmin connect 4.2.2
Fenix 5 7.60

update 2
I weighed myself
after 2 hours
normal sincronization and deleted the data
fenix overwrites the data

UPDATE: I've been on Gramin phones support here in Australia this morning. Re-described the problem and all the tests/re-installations/resets I've done. I strongly encouraged second level support to view this thread. After some discussion while I was on hold they issued an RMA so I am sending it it for them to do what ever they do. They were quite interested in this parallel issue that I have: https://forums.garmin.com/forum/into-sports/health-fitness/index-smart-scale/1297732-software-both-up-to-date-and-not-up-to-date

May be worth everybody checking to see if they have the same issue as well. And it is certainly worth you actually calling and holding for support. Even if this doesn't get fixed, awareness at Garmin Support will be raised.

Update: I think I have conclusive evidence that this isn’t the fault of MyFitnessPal. As per my posts above I disconnected that and have had a number of days of data not being lost at the start, but now it is routinely lost. The only variables are that the Fenix 5 x software was updated and Garmin pushed out one of its regular updates to Garmin Connect mobile IOS.

NOW my data disappears as soon any activity syncs.

Please can all reading this with issues call Garmin support. I think it is clear that this hinge isn’t squeaking enough for Garmin to pay attention.

I am am going to give them on more chance to address this before returning the scale to Amazon.

DB00 the problem of deleting data on garmin connect takes place equallyciq.forums.garmin.com/.../1299063.png

I have the same problem of deleting data and the availability of an update that actually does not seem to exist.

Same problem here, starting last week my scale only save weight data, I cannot see any other data.

GARMIN please fix this issue,

I'm having the same issue with muscle mass etc disappearing. I also have weights for days that I didn't weigh myself. I suspect my forerunner 630 is writing data back to Garmin on update. I don't use my fitness pal
