It does seem fixed now, no screen going off, android auto connecting regularly, not staying off.
The car was left 1day, they could not re- boot,so left a 2nd day and mid morning had a call mid morning it had been done successfully.
Note we were told it was updated on purchase( clearly was'nt, as we were told the screen might still turn itself off.
From talking to a car insurance repair friend, there is a lot of problems regarding software because of the " in isolation" need from the Chinese manufacturer.
Anyway if yours is updated expect to take a while to get completed
