If you search in youtube you can see a lot of fishing machine but its impossible to do all of this tutorial in the bedrock edition cause There is a difference between the pc and the bedrock edition
when I fish and when I keep the action button pressed and when a fish bites a hook it does not recover automatically the fish unlike the pc versions which allows this
we so my request is if you are able to fix thats will be cool 

Thanks a lot and see you 

PS : sorry for my bad english im french
