My provider offered me a new Fritz Box 7590 to replace my 7581.
I was a bit apprehensive of what that might do to my configuration, but updates are important.
In the process I had to hand the 7581 back in, so there was no way back.
But the result confuses me. The 7581 integrations say they need reconfiguration and no 7590 integration shows up.
What is the correct way to clean up this mess?
