I tried every ways to find communities from other instances. Searching for the url, searching for !communityname@instance.com, with the filter “all”, and I always get no results.
Those are communities that I find in other instances and would like to join. Nothing works.
How do you do it??
Dude, you’ve fallen out of the tree and are hitting every branch on the way down. If clearing your browser cache doesn’t work (which may log you out of other websites unless you use advanced browser features to wipe the cache for just your lemmy instance), I’d make a new post in this same community. If it’s not your browser, maybe there’s something funky going on with the server itself… and they do watch this community for bug reports. I don’t have further advice on this front though, and can’t test as my account is on a different instance.
Good luck. Although Lemmy has no shortage of sharp edges, I can say you’re having a considerably worse than average day right now. If you get this stuff sorted, it’s… not exactly polished… but nicer than this on the far side.
