Thanks for that dude. I just started playing on my PS5 for a bit because my daughter was using my Xbox to play Minecraft. When i got back on an hour later I got the message that another device is logged in. I freaked out, but seeing your reply gave me a sign of relief. Fingers crossed it works itself out.
@PapaPonchoo I get the same message when switching between my PC and Switch.
The way I've found to quickly switch between the two platforms is to do the following:
1) Whichever platform is logged in, return to the main menu of the game and wait a few seconds
2) With the first platform still on the main menu, boot up the game on the other platform, and it should let you jump into the game
