Hi,
I've installed the new iOS versio (13.x) this week on my iPhone (8). Since that time, the BT connection with the Columbus is not as efficient as it was.
Each time I get into my car, the PIN code is asked, where as it wasn't on iOS 12.x
Once the (correct) code has been entered, the Columbus seems to try to synchronize something without succeeding... I've driven for 25 mn yesterday and I still got the "Please wait" message on the Columbus once I had reached my destination
