Hi @brunoerusso,
Customer feedback is one of the most important things we take into consideration when building and improving Insync. Seeing it as trash is the last thing that we want users to feel, and I would like to apologize for the issues and troubles you’ve faced while using our application.
As for Flatpak, we have explored this exhaustively in the past but have decided to shelf it (not permanently) as it presented certain issues that caused significant limitations in further developing support for it. We are happy to circle back to it as soon as our team’s resources permit since there have been plenty of input from this thread alone.
As for OpenSUSE, this is not an officially supported distribution but we have a repository for it. I’ll send your feedback to make sure that repositories are maintained. Thank you so much!
