Answer
No — according to IFS Support, the Apps8-era mobile framework (MWO Apps8) is de-supported by R&D and was built targeting older Android versions, predating Android 10's release, so it isn't expected to work correctly on Android 10 devices. If issues appear after an Android OS upgrade to 10 on a device still running the Apps8-era mobile app, the recommendation is to not upgrade that device's OS version, and to downgrade back to an older, Android-9-or-earlier version if the upgrade has already happened, rather than trying to fix compatibility with the de-supported mobile app itself.
