For minecraft bedrock beta 1.16.0.51

I am a beta tester for minecraft bedrock 1.16.0.51 and I have been experiencing crashing most time but as well as the trading system with the piglin I have found if you hold a gold bar in your hand and go up to the piglin it shows a text saying action.barter and I recently had found out there is no other trading besides flint and obsidian.
