Custom Transparency Mode automatically turns itself off when I connect my AirPods Pros 2nd gen

I use my AirPod Pros as a substitute for my hearing aids (this has been approved by my audiologist, and has my audiogram installed in the accessibility settings), and I use the expanded transparency mode menu (Settings > Accessibility > Audio/Visual > Headphone Accommodations > Transparency Mode > Custom Transparency Mode) to increase amplification, reduce background noise, and boost conversation range.

These features are things I rely on to function for my day-to-day interactions and work (I work in film and tele, hearing comprehension is pretty important to do my job), but every time I put them on the Custom Transparency Mode has turned itself off so I have to go through those five menus to find the setting to turn it back on again. Every time.

I have factory reset and unpaired my AirPods four times so far to no avail.

This happens on all my connected devices (iPhone 12 Mini, 14 Pro Max, 11” iPad Pro 3rd, 4th gen iPad Air, watch Ultra, 2012 MacBook Pro running Mojave).

I have contacted Support, they seem to think that turning off Transparency Control on the arm of the AirPods will fix it, and it did for one connection, before the problem continued. It seems to be consistent when I connect after being disconnected for longer than 20 minutes. It’s also occasionally disconnecting the Custom Transparency Mode while it’s still actively paired with the device.

Is anyone else having this issue, or have any solutions? I feel like my issue is pretty niche
