I also got the same bug and the same procedure too. In addition, I found another bug, which is not being able to add tags in Anytype’s built-in Relational Tag (can’t be clicked) and not showing under Title and Description.
Yes. All relations created with the type relation ‘Tag’ are locked everywhere. This seems to be happening when changing back from pre-release to release versions on Windows and the lock on ‘Tag’ seems to sync to all devices as well. Now the lock appears on the same account but on Android as well.
This is in addition to the spaceType1 bug mentioned by @anon
EDIT: The user created relations of ‘Tag’ as well as ‘Status’ are locked from editing. They do not appear locked when looking in the Library. Custom Relations of ‘Tag’ and ‘Status’ created after change to Release work fine.
This is not a bug, this is because you have used version that updated type of your space but older client does not have a localisation string for it. Update to 0.36.0.
