Usually when I reach the end of the feed, it just loads more. But recently, I started getting a bad request error instead. Not every time I reach the end, but once I get it it doesn't go away when I tap on retry.
Is anyone else seeing this happening? Is there anything I can do to fix it?
Likely is. I'm experiencing something similar with timeouts instead, but it happens across clients (and less often since a server upgrade). So probably a change in configuration for your instance, or an uptick in usage/growing userbase?
Either way I'd check to see if this happens on other clients too, first.
