Hello,
Upgrading from the old version 3.9.3 to one of the 4.x.x versions (4.0.0, 4.20, 4.6.0) always ends in an error:
Your database migration failed:
Failed to load the App “Poll” (c33fa1a6-68a7-491e-bf49-9d7b99671c48) as it requires v1.0.0 of the App API however your server comes with v1.28.0
We would be grateful for any help,
Regards,
Michal
