13.1.2 Bluetooth no working with uconnect

So over the last week Ive been doing a little testing.

100% of the time (25+ times) when starting the car at the back of my property or out and about with the phone on me and no apple watch on it connects fine although twice it connected the phone for calls but didn't connect for music and I had to manually click the music device connection and it would then connect without issue.

Around 50% of the time (10 times) when I would start the car while either wearing the watch or even if I started the car from the front of my property which is right next to my bedroom so the watch would be in range of my cell and I assume still be connected on some level the Iphone 11 pro would not connect to my 2012 Chrysler 300.

The reason I still think its on the uconnect end is as follows;

1. I had this issue with my last iphoneX for the previous 18 months around twice a month. It was noticeable enough to me that I would only start my car in the morning to warm up if my iphone was left in the kitchen next to the driveway so the phone was never out of range of the car.
2. I previously noticed with the iphoneX that if the car connected and then I took the phone out of range of the car it was 50/50 if the car would reconnect when I went back into range.
3. If the car didnt connect or lost connection due to range the only way to reconnect was to turn the car off and leave it off for 5+ mins. No amount of button clicking in either the bluetooth menus of the car or phone would ever get it back. If i lose connection due to range in my van with a pioneer headunit I simply connect again via the bluetooth menu of the iphone and 100% of the time within 2 seconds its reconnected.

My conclusions from reading the posts here and my own experience are;

1. It appears that if you have any device connected via bluetooth (not limited to just the apple watch seeing others have had the issue while wearing other brand smart watches) we run the risk of our phone not connecting to uconnect.
2. It seems to only be an issue with unconnect and iphone as others and myself have no issue with connecting to any other brand headunits.
3. The later your iphone model is the greater your chance of seeing the issue

Let me know what you guys think
