MyChevrolet App No Longer Works

[DanZ]

I had a fully functional MyChevrolet app on my android phone, but now it no longer works. I have tried all of the following, trying to troubleshoot the issue: 1) I have cleared the cache, 2) I have cleared storage, 3) I have uninstalled and reinstalled the app.  Every time, the app freezes on the "OnStarPIN" screen.  If I enter a PIN on the screen (the same PIN I had already entered at the dealership a few days ago), nothing happens--I stay on that screen. If I tap on the back button at the top left of the screen, I get a totally blacked out screen, and again nothing happens, it's stuck on that screen. If I close the app, and go back into it, once again I'm on the "OnStarPIN" screen, and can never get past that screen.

(Note that my wife was successfully added a couple days ago as a family member, and the MyChevy app on her android phone is still working.)

Please someone at OnStar do whatever you need to do, so that I can use the MyChevrolet app again. Thanks.

To add further, I saw this particular thread and all already tried all the steps outlined in that discussion:

Power Cycle Steps: 

1. Enter the vehicle and turn ignition on (Vehicle should run for at least 60 seconds)
2. Shut off vehicle 
3. Remove Key from ignition or Press start/stop button
4. Exit vehicle-Key FOB must also exit vehicle
5. Close Driver’s door-All other doors, hatch, liftgate should also be closed
6. Lock vehicle doors using key FOB
7. Critical Step: Wait ~ 2 minutes ( or until OnStar LED goes out. This allows time for the OnStar unit and other electrical systems to turn off)
8. Re-Enter the vehicle and turn ignition on

Android Cache Clear Steps: 

1. Tap the recent apps/app manager button to view recent apps
2. Swipe left/right to close the mobile app
3. Open your device settings
4. Select Apps then Storage
5. Tap Clear Cache
