Although this "feature" of no longer being able to set the charge limit from the charging screen is being discussed in another thread, No charging options in v11 (Legacy Model S/X), it may mainly affect legacy Model S and deserves some recognition in the Model S forum. Currently with v11, the only way to set the charge limit (something I do frequently), is to to get my phone, unlock it, open the Tesla app, have it connect to my car, select charging, then try to adjust the tiny slider to 80% (or whatever). Hopefully this is recognized as a bug, or oversight, and quickly corrected.
