Same here, using Xiaomi Mi 9T with Garmin VivoActive 3. It does seem to sync when i have the app connected, but i dont receive any smartphone notifications on my watch.
I get this too - followed by the text "Android notifications have stopped unexpectedly. In order to restore notifications for your Garmin device, you will need to reboot your phone." I do nothing and things…
SOLVED the issue on my phone (mi 9t).
It was under battery saver options. I had to turn of "use adaptive battery"
Maybe your phone has a similar option, it's worth to check it out.
Same here, same phone and Garmin as Edmund, Really annoying..

I recently updated my Huawei to EMUI 10.0.0 and had to make sure that my connect app wasn't being managed automatically. Here is how I change it. My phone model is YAL-L21 but I am sure this will work if you have that latest EMUI update.
Phone Settings > Battery > App launch > Connect > Manage Manually.
I did this for all the Garmin apps on my phone too.
