Android user here. App's been painfully slow lately. Have to close it multiple times/day after I've played videos back to back to get it working again, to get comments to load, to be able to scroll smoothly through comments, etc. And for the love of God, please, PLEASE, fix your bot problem, there are SO many pornographic bots it's disgusting and out of control! I will stick to using browser on my phone to browse YouTube, it works smoother at this point unfortunately.
