All devices vanished from my eufy security app

Since several hours now, all my devices have vanished from my eufy security account - this coincides with the software bug reported today. It is like I never had them, the app simply asks to add the devices again. Could you please help me recovering my account devices? I own a HomeBase 2, 4 Eufy cams 2K, a tilt and pan cam indoors, several devices for detecting open doors. All gone.

Installing everything again is not an option. The cameras have anti theft detection and I cannot remove them from their place (now that they vanish from my app), can I? Please help.

I did uninstall and reinstall the app, logged off and back in, nothing seems to work.
