I don't have any official information on this but this is the information i
have gotten from multiple people aswell.

The problem is that if you start on channel 1 and switch to 2 it may work
but then it fails when you switch to channel 8 and after a restart of the
backend you can go from 1 to 8 and then maybe channel 2 will trigger the
problem and so on although i have noticed that some channels seems to
trigger the problem more easily.
