Technology fun.
Part 1.
Car head unit working fine with android auto.
Had a Google play update.
Now connection error.
Forum suggestions uninstall google play services. All good, works again.
Go to buy something and phones tap and go isn't working. Payment Card has disappeared. Have to walk out empty handed and figure out problem.
Fiddle around adding card again.
Today google updates play services. Breaks head unit again.
Latter to to pay and it doesn't work. Card is there though. Have to click through t&cs and get card installed again, whike waiting at counter.
