Minecraft Realm error expulsión

Hi! I'm having a serious bug with the Bedrock Edition (Android) Realms. When I'm building, I get lag, then I get kicked out, and when back in, everything I've built is deleted, as if it's undone or not saving what I do after the lag. It's very tedious having to build the same thing two or three times because of this bug. I say bug because I checked my internet connection and that's not the problem, since I tested it with other games and they work fine. Please fix it. This bug started with the latest update; it didn't happen before. I've attached some screenshots. I'm building a palace with a lot of detail, and it's frustrating that my work is being deleted because of this bug. There you can see my progress on the palace, and in the other screenshot, after I got kicked out, everything I did was deleted, and it went back to the beginning.
