Deletion of Structures on MCPE Realms

I logged onto the Realms server that is shared between a group of my lovely friends, only to find out that the majority of our structures and buildings are GONE. We spend a lot of time building a beautiful spawn area, which resembled a small town square and 3/4 of it is gone!!! There is only half a building and a few trees. Meanwhile, everything I've ever built has been deleted, and the same thing goes for my 5 friends who are often active players on the server. I don't know what kind of bug or glitch this is but this is unacceptable. Excuse me for sounding like a Karen here but we've been working on the growth of this server for months now! I don't think there is any reason to place blame or accusations on anyone or anything specifically, but something needs to be done because I'm sure we aren't the first people to have gone through this. We are devastated. My poor friend called me in TEARS. It was just a mess! I am beyond disappointed. So please help if possible. We all love playing Minecraft and would hate to have to remember it so bitterly. Don't let me have to find a Mojang email account and send a strongly worded message their way 🙂.
