I was just playing the 20w14a snapshot and every time I try to use my axe when its in my off hand, it doesn't work. I thought if I changed my off hand it might be fixed, but it didn't, I then tried having my main hand empty. That still didn't work. I'm assuming this is the case for anything in my off hand, but I didn't check so I might be wrong. If i'm holding an axe in my off hand, and a shovel in my main while at the same time looking at wood, please make it be able to recognize that if i punch it ill want to use the axe.
Thanks.
That's an intended feature, your offhand can only do right clicks. If you want to break blocks with an offhand item you'll need to put it in your main hand
