We are aware that the 1.19.60 update is causing some performance issues for players on Switch. We are actively looking into solutions and hope to have the issues addressed as soon as possible. Thank you for your patience and we apologize for the issues caused. jhp

I posted about my Realm before, but I've recently found that I can't stay on my friend's worlds for very long either. It kicks me out of both within minutes, and out of the public servers, including The Hive. My internet works fine, and both my PC and Switch are updated.

Hmm, it's odd that it kicks you out after some time, rather than just not letting you in. Have you tried any troubleshooting so far, such as testing on a different network? ^LK

Do you have any old packs or worlds you're not using on the switch? It can be a bit finnicky so removing content you're not using can be helpful. ^TK

Apart from the Super Mario pack that came with it, the only skin pack I have on the Switch is being utilized. As for worlds, I can think of two I haven't done anything with in a while.
