I completed the upgrade from iodeOS 6 to 7.7 last night on my Fairphone4, using adb sideload.

I did a factory reset/data wipe.

Most of my apps were restored via a Seedvault backup (with APKs).

Issues I’m having are app related, not iodeOS, namely:

- my password manager Proton Pass crashes. I reinstalled f-droid and got an older version of the apk to work from there
- my main banking app N26 is totally borked. Aurora Store knows about the app, but lists the version number as v0. Does not run, this is a huge issue for me. Any tips / leads would be appreciated.

Thanks
