It has long been possible to activate two pistons that are one above the other at the same time with just one redstone on top of the block above them, but only in computer versions. However, in versions for mobile devices (Android and iOS), this is not possible, as the redstone only activates the piston in contact and not its neighbor together. This makes it very difficult for pistons to be useful for making some tools such as automatic doors. I believe it's time to add this function for accessibility of using pistons. I've been waiting for a long time for this leveling with the function that is already present in the java edition, however, so far nothing so I decided to alert you.
