Can't transfer items all at once.

Doesn't matter what device. The issue is the same for all devices. Me and my 7 other family and friends are having the same transfer issue. When we try to transfer stuff to a chest and hold it down it only sends one or 2 items. We are not too happy with this glitch because it takes so much time to transfer 64 itemsand it glitches and show u haven't transferred as much as U have. Also people have been losing items. Please fix it. We enjoy playing.
