It might have been reported in this forum before and it was somewhat to be expected, but I have just read the first FP2 user (in the German language Facebook group) report that confirms the well-known issues with SD cards formatted as “phone storage” (internal storage) under Fairphone OS 22.02.0-rel.0 (Android 10), too.
If my memory isn’t completely wrong, the issue started on the FP3 with the Android 10 upgrade, too.
A recommendation to FP2 users with “internal” SD cards still on Android 9 to switch the card to portable storage prior to the upgrade probably does not hurt.
