Bluetooth connection is very buggy since updating to iOS 18.4. Beta X (with all betas) Airpods Pro 2 most of the time don't connect directly with my Iphone 15 Max. I have to disable bluetooth and then the connection works find. This issue ist not only with my Airpods, but also with the car, ... Very annoyinig. I reset the network settings. But this didn't help. Any suggestion how to fix this? I hear from quite a few people that they have bluetooth issues with iOS 18.X. Hope Apple fixes this soon.

when I receive calls on my mobile number and I am connected to a Wifi, the calls is cancelled after the second ring and the caller receives a busy signal. That means I cannot receive calls anymore. This problems happens with different mobile providers and does not occur on my Samsung Galaxy Phone with the same number (eSim). Even when I disable WIFI Calling the problem persists, when I am connected to a WIFI. Only when I disable the WIFI Connect and I am only connected to the mobile carrier, the calls go throuhg in a normal way. VERY annoying and hast not been fixed with Beta 3 of iOS 18.4. Any clue how this can be solved with settings? Hope Apple fixes this very soon!
