The workarounds dont mention how to troubleshoot android . . .
Using android as are 2 others on same wifi. No restricted skins. Latest version. Two tablets can connect to each others worlds but not mine,(smartphone) and I can only connect to theirs if I connect to a server world first, (this does not work for their connection to me). Tried resetting wifi rebooting devices. Not cross platform but still happening. Only started 2 days ago when we updated minecraft (two updates in quick succession), no problems previous 6 months of playing together. No changes to our setup other than two recent minecraft updates .
First symptom was shortly after updating to 1.16.20. my world appeared to stay available to join under friends tab for about 6 hours after I had quit out (there had still been 1 friend with me in the world afk) (showing 2 of 5 friends) and even when I loaded or created other worlds they were not visible, only the old one. This old world showed v 1.16.20 despite my having updated all 3 devices to 1.16.40 shortly after quitting it. The broken world eventually disappeared but now I have no luck connecting as described above
Same issue. I create worlds on android and even though others on same wifi can see it, when they try to join it says unable to connect to server. I had the same issue connecting to theirs ( also android and they connect to each other ok). I managed to connect to theirs once after joining a server world and quitting it but this does not help them join my worlds. Using newest version. Restarted turned wi fi off and on. Not resolved
I had several armorers and smiths with really good armor/weapons switch to farmers when I put down composters. Meanwhile jobless villagers never choose a profession, and just wander around aimless, even if I put a new job block in front of them. If I break an existing job block, the villager immediately switches profession while the jobless remains jobless.
All of my existing villagers with established jobs of which I regularly trade with just randomly switch if I put down new blocks instead of jobless villagers claiming them.
I've spent countless hours grinding for trade resources to upgrade their levels and get decent trades, and then they just switch jobs spontaneously. Extremely frustrating.
