Steps to reproduce the behavior:

Additional context
As soon as I deleted device and after that create new one with the same token, Everything start working. It looks like some bug in memory or cache after cloud update.

I dont want to delete devices, because I would lost data. Maybe there could be

Any help or command to clear cache or anything else?
