Can`t get any connection to preheat or charging info. with my T app in cellphone . I can get info. about " find my car" and "latest trip" but not  preheat or charging info. I can pre heat through the AC button at the key but not in  the phone app. I haven`t had the car  at  service so no disconnection by the toyota garage and I`ve tried for some 40 hours now Any suggestions on solving the problem?
