I have charged my pixel buds and now the left bud will not show up. I have forgot them in Bluetooth settings and repaired but nothing is working. Only the right bud and case show up. Right bud is working.
It could be the left bud battery has completely drained. I suggest you clean your buds: https://googlesupport.serverhump.com/googlepixelbuds/answer/9112670?hl=en
