Indoor Cams Offline - No More HomeKit

Started 2 days ago. All Eufy indoor cams started sending me motion detection notifications (I have these turned off for the Eufy app). Only HomeKit is set to notify me. I looked at HomeKit, all Eufy cams are “not responding”. All Eufy cams in the app have reverted back to default settings - Status Led was on (I have them set to off), Watermark was set to Timestamp and Logo (I have only Timestamp set).

What happened to cause this? I also can’t add them back. Restarting them doesn’t do anything. I can still access them all in Eufy app.
