Yeah, MAS jumped from all of the sudden from 0.2.something to 1.0 - very well... And that is all with 136 issues opened, including the issue when the user won't be created as it should.
I've ejected Synapse from Cloudron and run it independently - it is kind of working (if you don't mind get your hands dirty in the database), but if you don't need Element Calls - I can't see no real benefits.
Not sure if the question was anyhow directed on me, but I hope that rant might be of some use anyway
