iPhone 7 Google maps delay on bluetooth
I use my iPhone 7 with Google Maps in both cars, connecting via bluetooth and set up as a bluetooth phone call. It has worked fine like this for years.
Recently both cars started missing the first second or so of the voice directions. e.g instead of saying "In 300 yards turn left" she says "...yards turn left". It's very frustrating.
I recently changed ISP and now have wifi calling turned on on the phone but I don't think it's that. I've tried turning it off and it makes no difference.
It still works fine if I have music playing via bluetooth in the cars so it seems to be a delay starting bluetooth or waiting until the link is established before starting the message.
Any ideas?
iPhone 7, iOS 14
