Collabora - Issue protecting spreadsheets with password

Hello dear community,
unfortunately I have the problem that spreadsheets (.ods .xlsx) and digrams (.odg) can not be protected with a password.

After setting the password/pressing ok, the error message “(Username) disconnected” appears.

I have the same error also with Collabora Built-in Server. However, there the error message is slightly different.

Interestingly, setting the password, changing the password and opening the file works for text documents (.odt).

Anybody have an idea? :slight_smile:
