[17.24][17.26] Lags, Freezes and missing data

Today Connect sync HRV and sleep data from the watch as usual. Only yesterday datas are missing ( but there are on the watch).

How does the Garmin Support Center help with this problem?

A further update from my side: 

Last week, after travelling without my cable and experiencing these problems, my watch ran out of battery for two days. At the same time, my phone updated itself to a new OS (samsung ONE UI). Since then, I am no longer having any of the problems anymore. My watch face is responsive in the morning, no lag, and battery is only dropping at about 7-8 % per day (no activities). 

Unfortunately, I cannot give a clear answer on what fixed things. My suspicion is that it is maybe something with the link between the watch and the app on my phone, and that maybe the huge update of my phone OS and probably also of the connect app on my phone is related to why things now seem to work fine. 

My Garmin forerunner 255 music is missing data major chunks in days i dont know what happened its not even showing on connect as well as garmin express.

The same problem 

Is your Garmin new as well?

Does it sometimes restart too?

What are you doing to resolve this error?

Did this start happening after update as well?

I wrote them a mail.

I bought it last year, no problems at all since last update. Restart, freezing, lagging. I suspected bad firmware revision until I check this forum, finding a confirmation

I don't know what's the issue replacement of watch or wait.

Hi quick question the data on watch is all there and getting recorded on watch but somehow is missing from connect app in my case is that the issue with u too?
