Issue:

When Transferring a world from Nintendo switch edition that has "Trust Players" DISABLED on Nintendo Switch Edition, you are unable to Break / Place Blocks, OR Hurt Entities. The world tested was a custom Superflat.

How to Reproduce:

Create a world in Minecraft Nintendo switch edition. Make sure its a Superflat World. (and in creative mode) Also Make sure to disable "Trust Players". Join the world, then leave it. Open Minecraft Bedrock Edition and sync / transfer the world you just created on Nintendo Switch Edition. Still on bedrock, open the newly transferred world. Now, Attempt to Break a block, Place a Block, or hurt an entity. If you Followed all these steps correctly, you shouldn't be able to make any changes to your world.

UPDATE:

Current "Fix":

Ride a horse (it may take a few tries to get on it), then immediately dismount it. You will now be able to edit the world, BUT you still cant use Commands (even as an operator)
