myChevrolet App: 'Vehicle Status' and 'Widget' Issues

I currently have 2 vehicles that I use with the myChevrolet app.  A 2015 Chevrolet Colorado and a 2019 Chevrolet Equinox.  I currently have the following 3 issues with both vehicles:

1. "Vehicle Status" > "Fuel Efficiency" - Not working - No selection for "Lifetime" or "Trip A" (Both vehicles)

2. Widget, when installed states "No Data Available".  No option to select vehicle when installing. (Both vehicles)

3. "Vehicle Status" > "Tire Pressure" > "Recommended" Front and Rear Tire Pressure states "34 psi".  Should be "35 psi". (This was correct back in February in older version of the app.)(Both vehicles)

I currently have 4 open cases with OnStar, Connection Center,  Executive Escalations and myChevrolet app support.  Issues started when app was updated earlier this year.  Still no resolution as of August 3rd, 2022.
