apple carplay Apple carplay won't connect sometimes. (Wired connection)

[Todel]

Hi, in my Audi A4 2015 the apple carplay feature is rather inconsistent and sometimes it won't work at all. I have two ports for the apple carplay and both of them seem to be the same. It works most of the time but if it's not worked for the initial start up of the car it won't work until the next time it's started again. The phone always gets a connection as I can see it being on charge, however the apple carplay won't be working. I have tried using different cables or phones and that does not change anything. I am unaware if this could be an MMI software issue where I have to update the version of it.

Anyone seen this issue before?

Thank you in advance.
