When I started playing the update I was really excited. But I noticed something weird. When I would try to destroy blocks they would come right back and take several tries to destroy. Then I noticed when attacking a mob 30 clicks could result in two actual hits. Also sounds had a possibility of playing after the interaction that caused it. So I restarted minecraft hoping that would help, it didn't. Eventually I figured out if you're on anything except peaceful these things happen. I hope you can find and fix this issue so everyone else can benefit from this.

Thank you!

Update: On peaceful you can't collect the blocks.
