Help - Checking Status/Fibaro Relays (FGS212)

Anyone else struggling with the app? I’m getting ‘Checking Status’ notifications for such devices as Fibaro FGS212 even if I change the DTH to the latest published version. Any help VERY MUCH appreciated!

I thot new app didn’t handle much if any custom DTH.

That’s why everyone that wants custom, uses “classic” app.

I’m new to Smartthings but my understanding is that DTH are published via SmartThings Groovy IDE environment. Are you saying the SmartThings App (not the classic version) doesn’t support the use of these published DTH?
