Same thing is now happening to me. Last night I got a message about my database growing (1000+) so I tried rebooting a couple of times but the message didn't go away. This morning I got a currupt database message so I couldn't access anything in my hub:
I did a soft reset (downloaded a backup of course) but no luck getting back into my hub afterward. This is all I see when trying to access the hub from my computer:
As OP did I will leave it alone for an hour.
Another question, does a backup contain all apps and automations? In other words, will it revert exactly as it was before the soft reset?
