morning everyone

Im having a problem with my Blue and Me. I updated the software a few months ago and it was working perfectly, however, recently it has started to get worse. First it showed the names differently from how it used to show them, then in my recent calls list i noticed a few numbers starting to disappear. i am now at a point where the recent calls only shows landline numbers and not mobiles. its infuriating as i only use mobile numbers (the landlines are when i have called shops etc).
I have tried to delete the user files in the car and i have also rebooted my phone (Iphone XS)
if anyone has an idea how i can resolve this it would be much appreciated.

Thank you!

Yep tried that one. I've updated the Blue and Me software again and ive also rebooted my iphone but no luck
