I tried to restore an old backup remotely, it was taking too long, so I did a soft reset and used the diagnostic tool instead.
Again, when I selected the local file to restore, it was still taking too long...
So I decided to open a seperate window, the UI was available, just no devices or apps.
I got feed up, then I just rebooted the hub again.
And, when it restarted it did have my apps and devices, but I am not sure if anything is missing or if database is corrupted in any way?
Will test this evening when I get home.
Thanks for confirming.
I will have to find a quiet period to try again and not upset the family.
(Intention was to restore an old backup to find a missing app, but I ended up restoring current version again).
