I tried to get the downgrade, but I can’t get it installed.
I got pretty far tho: rebooted in safe mode, downloaded the old verison als .zip file, launched it via the updater app, pressed install, reboot… and then I got an error.
I tried to find instructions on how to proceed but I can’t find the solution just yet (for example, here: How can I downgrade the fairphone OS to an old version?).
If anyone succeeds in installing an older OS version, please let me know how you did it and if it worked. Thanks!!
