I think miui optimization is already deactivated in this ROM.
To install YouTube vanced you only need to download vanced manager's apk in its official page, install it and in the app you have to install vamced micro g first and then YouTube vanced.
I used the weekly version until a week ago and couldn't use AAC. Did you ever stop being able to use aptx or is it an AAC only problem? If so, I will try the weekly again
What is your device? I used the weekly until they released the stable one because I thought AAC would work on the stable one but it doesn't,at least on the redmi note 8
I can't use the AAC Bluetooth codec in my Redmi Note 8 with my MI TW earphones 2 basic, also I have a problem with the wi-fi, this disconnects and connects so often, especially on 5G networks. I use the version 2021.3.10. Sorry for my English.
