Keep getting kicked out of game during game play since the new nether update. Xbox one / Bedrock edition

So I have a few issues going on. Since the new nether update, Minecraft glitches in and out during loading and gameplay. Sometimes my profile avatar doesn’t load. However, the most frustrating thing during gameplay is - the game freezes and then completely bumps me out all the way out to my Xbox home screen profile. Also during game play, when starting a new map, I notice the map doesn’t fill out as it should. There’s a major lag effect. So instead of the map being filled out in a smooth wide rounded view, instead it’s filling parts out looking more rectangular/square. Basically it looks botched. So between all the lagging and constant kick outs during game play I’ve  been pretty frustrated all day. Please fix whatever is going on. Thank you kindly.
