Alert Zone not saving (app version 4.160.319 on Android)

Less than a week ago, I noticed my Alert Zone is not saving. The old setting persisted, but I have recently changed the layout of the room.

Here are the approaches I have tried to resolve:

• Tested it on my wife's login (on a separate Android phone)
• On my phone, I forced close the Nanit app and reopened again.
• Restarted my phone
