Tom, that seems like what I saw yesterday. I am going to continue using the save and copy method for the time being.
Like you said, loss of data issues need to have the highest priority. I definitely have not been as eager to play with the constant fear of progress being lost.
Jon and Tom, was the fix only for Realms?
What about regular non-realms worlds?
I am still testing but I think I still am having the syncing issues between two consoles. I need to test more as I think the copies upon copies of a single world may be messing with things. I am going to play some during lunch today, save, and delete all the other copies of this world and see if it syncs to my home Xbox this evening.
I am having a similar issue with syncing between Xbox consoles.

I also have this issue (I am on the Beta Ring as well).
Yep, I am seeing this on Xbox One (Bedrock version) as well.
