I amb noticing that Twidere seems to manage better conversations in Mastodon than Andstatus (clicking a message in a thread in a Mastodon account, Twidere shows the thread whereas Andstatus doesn't). On the contrary, Andstatus seems to perform better with !gnusocial accounts. So both clients are far from perfect, each with its pros and cons. Difficulties (and diverging paths) in federation between mastodon and gnusocial servers does not help either. Well, gnusocial has no path, right now 😅
