Since the update, destroying blocks has become really difficult. When chopping trees, you can't chop from underneath or from above, only from the side, unless you start destroying leaves first and keep your finger on the screen. When mining, blocks can typically only be destroyed from below, and sometimes it takes awhile to find a block that will work. With any block in between, whether or not it works is variable. Increasing or decreasing sensitivity or turning on split controls doesn't fix this. The recent version has added a lot of new features that we have been waiting for, but this bug makes the game unplayable at times.
