App seems to be "crashing" to home screen, Android v 2.20.21

For about a year plus I’ve been in Mississippi with a moderately poor internet connection.
I’ve been running the Wyze app and a varying numbers of cams monitoring them with a 128MB Samsung Galaxy A next to my recliner. That’s the sole use of the Galaxy A. It’s been very good, until recently.
About a month ago the app started crashing back to the home screen several times a day while I know the internet is working fine.
For many months it wouldn’t crash at all.
Has something changed?
