Hi, I have similar issues with 2 of my hard drives, WD passport and elements on my M1 MBA.. These 2 drives work fine with my older MacBook Pro late 2013 on Mojave and my Windows setup but cannot seem to work well on Big Sur..

Hi Apple, This is still not fixed in iOS 14.2 GM version. my Iphone 7 plus on 14.2 GM is still disconnecting and reconnecting on my Bose QC headphones while concurrently on a zoom call which is running on my iPad 5th Gen running iOS 13. Please fix this asap as this is very frustrating to have it disconnect and reconnect.
