Version compatibility issues

SRL

Hello,

I receive an error message similar to "your file is not a OpenLP version 2 or version 3 file, or it is corrupt" when trying to open a .osz modified (or created) with OpenLP 3.1.1 on a computer running OpenLP 3.0.2.

I used three different files and each had the same result.

Is this normal behavior?
Is there any way to correct this behavior without upgrading from 3.0.2 to 3.1.1 (or downgrading from 3.1.1 to 3.0.2)?

Both in French:
Windows 10 with OpenLP 3.0.2
Windows 11 with OpenLP 3.1.1

Before posting, I searched this forum for an answer but have not found one.
Thank you
SRL

SRL Services files created in newer versions of OpenLP may not open in older versions. In particular the format changed between the 3.0.x and 3.1.x releases. We cannot backport changes.

Thank you for your response, raoul.

It may be a good idea to inform users about version compatibility in the 'Known issues' for the release as to let users decide if they should (or not) upgrade to a newer version.

Thank you again,
