Live traffic problem - strange (temporary) solution
Phone is about as 'vanilla Android' as it gets, Google Pixel 3XL, Android 10, TT GO v 2.2.3
The short version of the detective-work story is that as soon as my phone connects via BlueTooth to the car's infotainment system, live traffic disappears (car symbol top right with X). Turn off BT on phone, live traffic works. Very strange... but totally reproducible.
Obviously turning off BT and thus giving up hands-free phone and music streaming etc is not a long-term solution, and I've been in touch with TT customer services to see what they say.
This unfortunate experience has made me realise how incredibly useful the live traffic is in my part of the UK with its constantly clogged roads. And, dare I say it, I quite like the new app, although the search function is so slow as to be virtually unusable.
