I do not know if this is counted as a "bug" but I'll elaborate anyway. The New UI for editing a world is pretty good but it lacks one thing, the export button. I can't backup my worlds and it kinda pisses me off knowing that all of my effort in that world will be in vain. That's why i want the New UI to bring back the old export button

The old UI never had an Export World button on mobile devices. It is intentional that this button is not available on mobile devices, see MCPE-174595.
