I seem to have two separate garmin connect accounts with the same email.

As I advised in the other thread you opened, try following the instructions in the document of Garmin Suport Data is Missing from My Garmin Account After Syncing

OK, you crossposted the same topic in several threads, which makes it a little bit more difficult to follow you, since you add diverse details in different threads. I would be better to keep all your posts regarding this issue in a single thread, and to stop continuing on cross posting in other concurrent threads.

In the other threads you did not mention you being in China. Have you registered the other account in a different location? That could be easily the reason. I have already seen a case where a Chinese account was isolated from an account created with the same credentials in Europe (as far as I remember): So make sure to set your location in your Garmin account at https://www.garmin.com/en-US/account/profile/ to the right location you want to use. Then remove your device from the accounts of Garmin Connect Web, and Garmin Connect (as described in the document Data is Missing from My Garmin Account After Syncing), log out of both apps, and then log back and add your device again.

Given that I encountered a similar issue and the fact that his link to Strava was still working, it seemed to me that his issue might not be a different account issue. In any event, I received this email from Garmin support today:

"Hello,

We're reaching back out regarding the recent reports of an issue with the All Activities list or News Feed not displaying recent activities that were synced into the account. We're pleased to announce that this issue has been resolved via a back-end update and should no longer be occurring.

Thank you for bringing this to our attention and for your patience while we worked to address the issue.

Thank you for choosing Garmin,

As I wrote,  2924148 reported (in one of the multiple other threds he opened about the same issue) that he did have two different user IDs on the phone app and on the web, hence his case appears to be clearly unrelated to your issue.

How do I even find my user name?

is my user name 2924148? 

Thank you, I will try this. 

I will also just keep on this thread now instead of others.

I created the first one in China without a VPN but possibly created the second one with a VPN making it think I was in America. 

But i I did try logging in with the VPN turned off before I created the second account and it acted like my email did not exist. That is why I tried creating the second account, to see if it would let me. 

So why couldn’t I log into my account in the first place?  The only place it signs me into my original account is on the app. 

How do I even find my user name?

One possibility is that the web account uses different ID than your phone app. On the phone app, go to Menu » Settings » App Diagnostics and note the Displayname code. Then open the web interface, click your avatar in the upper right corner, and select the option View Profile. Now compare the ending code in the address line of the browser, with the code from the phone app. If they are not identical, you have two differrent accounts, and need to use the same one on both sides. You can log out of the web account, and log in back using the identification from the phone app.

Though you can still have multiple accounts even if the web and phone apps show the same ID. You can also try instructions from this support document - they may help in such case too.

And if you suspect your current location in China is the culprit, then change the location in your Garmin account to the original one, and try again in that way.
