I believe that this might be a simular issue. I noticed when I use my 2015 iPad Pro connected to my new iPhone 17 PM using a hotspot the connection dropped twice.
I never had a dropped connection with my iPhone 15 PM in the exact place?
Hi, for those who thought that ios 26.0.1 (released today) fix the problem... Nope still same with CarPlay. For my lucky I have new module which is working perefctly fine (Adapter Ottocast Play2Video Pro Android Auto CarPlay).
