Web/iOS versions of Xabber do it quite well, complete with videocalls and screensharing, etc.
Android version is in rewrite (decided to dump existing app because of tech debt issues), but I have zero reasons to doubt that it will work (hopefully by august).
iOS version is not yet released on Appstore because we need to work out some more issues (not too many), but I can give you access to it, if you're interested.
i wanted to try sync with two sessions;
I havent been able to create a group. After accidentally aborting group creation, i couldnt try again for a while.
When i git the dialogue open again, and filled all the stuff in, the create button simply doesnt react.
I have no idea of what you are talking about. Likely your are using a rather old version of web client. Email me andrew.nenakhov@redsolution.com, I'll schedule you a demo of our latest stuff.
(We're currently not considering everything ready for public release, thus apps available to public lag from what we ship to our customers and use ourselves)
It is a three years old version that uses stock ejabberd 2019 version. It is far behind our current state of the art. We plan to update it with the next server release, but we have only four hands each so it'll take us a while.
