That sounds more like an Apple Bluetooth stack issue at their OS level rather than something wrong with the Bluetooth chip/tech itself. It's where you should complain to Apple or ask for refunds/replacements.
Granted, Apple is not alone here since both Google and Microsoft really botched their Bluetooth stacks on their OSs. Especially Google who hasn't learned you can't treat your C driver/embedded SW like front-end JS code.
