I subscribed to a Realm and uploaded my world on 1/6/19. I invited my husband, daughter and son-in-law to my Realm. My husband and son-in-law accepted right away and joined the Realm with no problems. My daughter accepted a day or two later, but she was unable to interact in the Realm. We assumed it was an issue with her Xbox.

Yesterday she tried to join again and it still isn't letting her interact in the Realm. She logged out of her game, logged back in and still unable to interact. She deleted the game, re-installed and came back into my Realm and still unable to interact. We can see her and she can see us, she can move and walk around, but she can't break blocks, open doors, activate pressure plates, etc.

I downloaded the world back to my local console and she joined the world...like she has many times before...and the same issue, unable to interact when she used to be able to.

I then added my other daughter (who's never played in my World) to my Realm and then my World and the same thing is happening to her ID as well.  I can see her, hit her, etc. but she can't interact. It's as though their hit boxes are broken. 

Everyone is playing on separate systems (5 total Xbox One's) and on the latest version. Is this a World Corruption issue or a bug or both?

I know I can restore the world from the first day I created the Realm but there has been a ton of work done in the past week so it's really not an option to loose all the building that's taken place.
