Updated and volume buttons are back to controlling volume as they should be! Tested on the homepage and working fine. I tested in a thread with a ton of comments as well and at first the volume buttons were navigating between comments as they had been so I decided to check the settings where I was able to disable this setting (and then the settings auto-saved so that is also working!). I personally hadn't noticed the issue in the last fix for comment creation not always including the post but I'll keep an eye out in case it crops up in this version of the app. Thanks @kuro_neko@lemmy.ca for the quick fixes!
