Some of your post seems like you’re requesting a feature change for the new app version, so you might want to add your comments and vote in this Wishlist topic:
The issue with your device list order not remaining set after you arrange it seems like a potential bug, so for that I’d be inclined to submit a log from the app to Wyze whenever you see it happen again and then follow that up by opening a Support ticket which can be linked to the Log ID. This can help the engineers track and issue and know what to look for in a log.
Since you said that this is also happening to others in your family, I’m wondering if each family member has his or her own account. I don’t want to assume anything in your particular situation, because I know with the way Wyze doesn’t allow shared device users to have access to certain features people sometimes share actual Wyze accounts (e.g., spouses both using the same e-mail address and password to login on different phones), so it would be important to eliminate that as a potential cause of the problem, because if one person changes the device order on one phone, that change (using the same account) is going to be reflected whenever the Wyze app is launched on a different phone.
If you can eliminate that as the source of the problem, then, yeah, it seems like you might have identified a bug, so I’d log it and open a ticket.
