Download it from the playstore on an old phone and then export the apk using an app?
No need to sideload, just find the APK on apkmirror.com
If youâre not comfortable with that, then Monzo could provide a safe way to get it outside of the Play Store but arenât.
Surely ultimately, though, the Monzo Android app relies on at least some Google APIs that wonât be available on P40 devices, meaning that over time, the standard Android app wonât work so well?
