@nestort Yes, in some cases AndStatus doesn't retrieve conversation from a server, but shows only previously loaded messages of the conversation. Now you need to press "Sync" button in the Action bar to get the latest messages of the conversation from the server.
I see that I need to do this syncing automatically in any case, on every conversation opening?!
BTW I automatically monitor "AndStatus" word and the #AndStatus hashtag in all connected social networks using syncing Search timelines, so I received your mentioning AndStatus from several places.
Tip: #Mastodon supports search by a hashtag only, so please use #AndStatus for even better discoverability :-)
