Teslas official position is that no one should be using any third party apps. Asking a Tesla owner having issues like this "Do you have any third party apps?" is like a front line help desk tech asking a person who calls in for support " Have you turned it off and on again (rebooted)"?
Even though there is a reason for asking that question (because it works), sometimes people straight up lie and say "Of course I rebooted my computer" when they didnt, or act like someone insulted their intelligence by suggesting it. Same deal here. You tell people "do you have any third party apps?" and many bristle and say "No, I dont!" forgetting that they tried one 2 weeks into their car ownership, and "uninstalled" it, 6 months ago or something.
