Something wrong with the Vivoactive 3, 4 and Venu?

Hi guys

Sorry if I missed some post about it in the forum, but I'm receiving a lot of mails about crashes on my apps on the Vivoactive 3 and 4, which didn't happen before and which I can't reproduce on the sim.

Then I saw similar reports on the reviews of this widget BY GARMIN:

apps.garmin.com/.../6cb03839-6c01-42ac-8acf-6c54801cc9ae (Garmin Hydration Tracking App)

So I guess it's a generalized issue and Garmin must be aware of it.

Is the cause of this problem known? And solutions?

Thanks!
