Flatpak starts dividing in system and user

Since a few days I cannot install flatpak updates via the software center anymore - and if I want to install a new flatpak it shows:

Remote ‘flathub’ found in multiple installations:

  1. system
  2. user
    Which do you want to use (0 to abort)? [0-2]:

If I choose user all is installed as usual.
Weird development…

Thanks for your report, @mesiment is working on it, please see the next post:
