Passmann and sync problems

we’re having trouble syncing passwords. Passwords that we create ourselves are synchronized with the app. Passwords we share show up in the cloud but not in the app.

where could the problem be?

Showing / editing shared password is just not yet implemented in the Passman Android app.
I did some work at it and now have a pull request ready, waiting for review of a depending one.
