Car bluetooth issue

I have a nokia 6.2, I can pair it to my car but it will not connect the phone, I can play audio through spotify but when I try to use the phone it says connection failed. My previous phone was a nokia 6.1 and this connected brilliantly with my car. If any one can help me I would be most appreciative,

cheers

update: my nokia 6.1 has just updated android and now this has the same issue, so the problem is the latest android. Can Nokia do anything about this or is it an android problem?
