I was playing Minecraft on a realm (I wasn't the owner) when the message ‘a communication error has occurred’ popped up. This happens to me often, so I hit OK and kept playing. A few seconds later, I was kicked off the realm with the message ‘disconnected’. There were a few other glitches as well, one of which I’ve pasted in here. This occurred for the owner, who was playing on Xbox series X. He also said that he was phased into a wooden plank at one point. 1.21 is completely filled with bugs. Please fix this, and soon!
