I’ve only experienced this with the above car so far.
At first I got two buzz crashes when trying to save a tune for the first time (this car only), rebooted console, allowed me to save the tune but when I go back into My Tunes the tune is there but it doesn’t allow me to select it so I can’t do anything with it. It allows me to delete it, but that’s it. I can save as many tunes as I like but I can’t select any of them once saved. None of the statistical data is showing for any of the saves either, just orange warning symbols.
If I try to load a tune from the Tuning screen, I can see saved tunes but again I can’t select them to load them, or rename them, or anything.
