I am, all of a sudden, unable to make or receive calls in my C8. I checked my smart phone and it is set to share contacts, blue tooth is on. I went to my dealer and they had no idea other than to say I might need a newer smart phone? I got my 2022 C8 end of October 2021 and my phone was paired for me at the dealer - after that no issues making or receiving calls while in my C8. Any ideas anyone? Thank you for your help.
