Another strange effect of my #GoToSocial upgrade, perhaps coupled with my other problems – and I really don’t know who is to blame: the Toot! app I use just showed me all my recent direct conversations as “new” (with those weird bubbles along the left side). I don’t think the Mastodon Client protocol offers a “seen” flag so perhaps the messages all got new ids? I have no idea. It’s not very annoying just surprising.
@alex didn't gts only just implement the direct messages api? Maybe they were just never seen (from that api) by your client?
