I can confirm that this issue is still there on Sep 14th 2020. i have to log into ring app on my Samsung family hub refregrator every time after it goes to sleep.
Do we have any fix for this please? I have tried cleaning the cache multiple times and since we cannot just uninstall the app from fridge, there is nothing more to try.
it does however show when someone rings the doorbell, but i have to log back in to see the history or other stuff from ring door bell.
Please get us fix for this ASAP.
