The new Tesla V11 OS changes are significantly less confusing / frustrating than the Microsoft Windows 7 to Windows 10 which almost everybody has now forgotten about. The Windows 10 to Windows 11 OS changes created a lot of complaints which subside with use of the new OS.
Same confusion / frustration going from Apple MacOS v1 ("Cheetah") to current V12 ("Monterey")... or iOS v1 to v15 (current iPhone & iPad).
Software evolves. I suggest you grab a cocktail or coffee and spend 30 minutes learning the new TeslaOS before you need any of it features. Learning the new UI is the least you could do in lieu of RTFM. Spend another week driving it to learn where the features moved to. Actually make a point to use all the old & new features. THEN post complaints here and let Tesla Support know via Bug Reports.
I've done this with every 50+ software updates on our 2015 MS P85D+ and they all became second nature after the initial learning curve.
It take a Village to raise a Child. It takes a Village of TMC members to get Tesla to listen.
