Aptx adaptive issue?

Hey everyone, I have a pair of Fiio UTWS5 and it supports Aptx adaptive at 96khz. However when I try selecting 96khz in the developer settings, it immediately defaults back to 48Khz? Anyone know why or what it could be?

I've already factory reset my TWS Adapters. I've also factory reset my phone like 3 times. (Due to other issues as well :/ ) is there something I have to enable? It should just work shouldn't it? I select use higher quality but go into the developer settings and it 48 not 96?

Kinda frustrating that it's not working. Yes I did try them with another phone and it did work at 96khz. They do support LDAC now so I'm using that but at its best effort settings. I wanted aptx adaptive for it's better connection quality rather than sound. I know LDAC is better but I use these mainly for work and it kinda noisy here so sound quality isn't my main concern at work. I save that for when I'm at home lol.

Any help or ideas would be appreciated. Thanks!

*UPDATE * The issue has been resolved! Or never was an issue I guess? So I really started digging around seeing what was going on? The reason I was not getting 96kHz? Snapdragon sound. It automatically selects the highest sample Rate for your media. I only realized because I recently purchased earphones that are Aptx Lossless. When I checked it. It showed up with the toast notification that basically says "Device supports AptX Adaptive" then a following one showing "Device supports Snapdragon Sound". Those 2 meant I was on AptX Lossless. So I go into my developer settings to check out the sample rate. It showed 44.1kHz?!? It was worse than before! However I then decided to play a hi-res audio track. Then boom! I heard the momentary switch over and quickly went into developer settings. 96kHz.... LET'S GO!

So basically when I tried forcing a change manually it would not let me because the audio source just wasn't high quality enough. Now I never had a phone like this before which is why I thought something was wrong in the first place. No there never was. It just chooses the highest sample Rate based on your audio source. You can't override it so that's why I assumed it was malfunctioning. When in reality I was malfunctioning lol.

TL:DR - There never was an issue. Snapdragon sound selects highest sample rate based on audio source. Better audio file, higher sampling, automatically.
