[BUG] Venu 2 - FW 12.13 - Garmin Hydration app notifications showing black screen

https://forums.garmin.com/sports-fitness/healthandwellness/f/venu-2/324454/after-12-13-fw-hydration-notifications-vibrate-but-screen-is-off

After 12.13 fw update (yesterday) hydration notifications vibrate time to time, but noticed the screen is off and not responsive to touch if i want to see what notification is.

Only way to get the screen awake is to push button B for a few seconds and it briefly show (for 1 sec or so) the "do you want to add hydration' message and then all seem to be normal....happened twice so far and this screen off/black is only when the notification happen as otherwise rotating pulse and/or touching screen it wakes the screen as usual.
not sure if this is just my Venu2 or a thing in this new fw....
