Tested more with some other people. Pidgin to Pidgin:
- Still can't get Disroot to work.
- RiseUp seems to screw up with every other server except RiseUp.
- Autistici seems to work well so far with everyone.
Conversations to Pidgin:
- Group chat OMEMO doesn't seem to work with either RiseUp or Disroot, but somehow does with Autistici (?). The guy I was testing with was using honk.li server.
Keep in mind these results are preliminary. Probably will have more confirmations tomorrow.
Do you guys think it's PIDGIN that is the issue? If so, would, say, Gajim fix all the mentioned issues? Might try that tomorrow.
