I was playing on a minecraft realm owned by my friend, and I got off to do something. I got back on about an hour later, and the game would not allow me to play. While the my end says "building terrain" the people I am playing with see me in the game. They are unable to interact with me, and I am unable to move. I tried restarting my device, and uninstalling and reinstalling the game, but that didn't make a difference. Things I have read before claim that it is an issue with NAT type, and I do have a strict NAT type, but I always have a strict NAT type, and this has never been an issue before.
