I think the issue has gotten better but may not be resolved. I didn’t have to delete / reinstall the app, but what I did do was use Fordpass and close it when I was done. I found that using it and leaving it open would drain the phone battery from background processing.
I’ve been leaving FordPass up of late and did have one day recently when I had unusually high battery usage but checking the battery log, it was mostly phone, face time safari, and my bluetooth grill thermometer.
So it’s been working ok for me lately. If you’re having the battery drain issue, and you’re using FordPass, don’t leave it open on the phone. Once you’re done using it, close the app out until whatever needs fixing gets fixed.
