iOS 14.2 Public Beta 2 Bluetooth Audio issue

I am having issues with my Bluetooth Audio Devices. When I connect, they say in Control Centre that the Bluetooth Audio Device is at 0% volume, despite decently-loud audio coming out of the Bluetooth Audio Device. When I try to adjust the volume in Control Centre, the volume goes up (visually (the volume doesn’t actually increase)) but then if I even dare to touch the volume controls on my Bluetooth Audio Device, the volume goes back to zero and Audio stops outputting. I mash the volume up controls on my Bluetooth Audio Device, and bam! The audio comes and goes. If I hit the sweet spot on the volume control, the audio starts outputting, despite Control Centre saying the volume is at 0%. I try and adjust the volume through the hardware volume buttons on my iPhone, and bam! Every time I increase the volume by sliding the slider up (I’m running iOS 14.2 public beta 2 (so that I have the redesigned volume icon)) the slider goes back to 0% without even asking. This is unacceptable, judging how high Apple sets their standards, and if they do, they need to fulfil them. This issue wasn’t a thing on the iOS 14.2 public beta 1, or iOS 14.0.1, or iOS 14.0. Please fix this issue Apple as I have lost my lightning headphones and the adapter, and do not want to buy AirPods. Many thanks for the attention.
