QGIS 4.0 changed for project settings are saved (the XML structure). If you open project saved in 4.0 in any 3.xx the project settings will be lost. What this does is that if you open qgz project from version 4.0 in QGIS older then 4.0 it reads the xml qgs file in qgz, parses it, extracts all the Mergin project settings and resave so that they are compatabile with older versions.
Not an ideal solution as it may lead to bit of ping-pong with project files, changing them back and forth, but quite likely the easiest way to fix the issue.
Fixes #904
