Incorrect Recommended Tire Pressure In Mobile App

With an open case for over a year with OnStar/GM/Chevrolet, my 2019 Equinox shows the incorrect "Recommended Tire Pressue" for both the front and rear tires in the myChevrolet app.  My 2023 Trailblazer sometimes shows the incorrect 24 PSI and sometimes the correct 25 PSI.  This changed for both vehicles when I made a plan changes for the 2019 Equinix last year and the 2023 Trailblazer earlier this year.
