The new interface says "migration needed". So I hit the migrate button and chose automatic migration. I did this on all devices. Now I read "0 device migrated", and "migration needed". Moreover, on a laptop on which I installed Teamviewer today, it says the software is out of date. The device I am using is not in the list. All devices are listed offline, although they are running and TeamViewer is active. Something is utterly wrong with the new interface.
