When it comes to updating headphone firmware, which tool did they previously remove and now reintroduce.Because when it doesn't update automatically, it's nice to be able to do the update manually and not just wait for something to occur. If it "just worked", there wouldn't be a need for the tool that Apple removed, then reintroduced.
I cant say if it works or not for everyone, but my AirPods got the update without my even knowing there was an update so anecdotally it just worked for me (and my fiancé). Do you know the percentage of failed updates that weren't cause by things like not connecting the case to a power source or delays from the server to support the claim that people need to be able to manually update their firmware?
