I have encountered several problems comparing with Java Edition:
- it is impossible to place torches where there is water. In Java Edition it is possible, even if the torch is removed immediately afterwards, this allows you to recover air in Survival.
- it is impossible to put objects like torches, arrows in the secondary hand ... In practice only the shield can be placed.
- In Creative the bucket of water empties when you place something water. Sometimes you can go on indefinitely, other times (as in survival) the bucket empties with each use
