The update verification is not working for me.
I do see the XML file and the timestamp correlates to when the vehicle update was completed.
My XML file name is Sync_W08TBTY0_(vin of my vehicle). Is your XML file named similarly?
I used the upload link in step 4 of the instructions. Upon selecting the XML file for upload I see a green check mark indicating a successful upload very briefly then the screen immediately refreshes itself to a different page and I'm logged out of my account. When I logon again and return to the my Vehicle Dashboard I still see a notification that an update is available.
I tried two different browsers on 3 consecutive days.
My vehicle reports the update was successful and the correct version displays on the Setting page of the vehicle.
Perhaps my vehicle has a fractured software bolt.
