For both myself and others I know, every time we try to either put things into a chest or take things out, instead of holding it down and all 64 items are transferred, it transfers one at a time. So I'm having to continuously tap until all 64 blocks are in my pocket or in a chest (same for putting things into the furnace). This makes everything take twice as long and is quite frustrating.
