I have started playing on a realm started by someone else (I'm familiar with minecraft but new to bedrock so I'm not sure if there are other details about that which would be relevant, I've never started one myself).

When playing alone on the server, I have frequent connectivity issues and get regularly disconnected from the server. I'm not sure if this is a problem with my internet or not, but whatever. It's not hard to just enter the realm again. The problem is that whenever this happens, significant progress in game is lost, putting me back what seems to be minutes (up to ten minutes) to some arbitrary previous point. This just happened to me twice in a row, disconnecting and taking away what seemed like over 10 minutes of harvesting/building progress back to the exact same previous spot (the last time I connected to the server successfully maybe?).

This doesn't seem to happen when both my friend and I are on the server (at least not frequently or significantly, I can't remember it happening).
