Starting about 30-45 minutes ago, my Bedrock Realms server keeps booting users (including me) every 5-10 minutes and upon reconnecting all progress since last login has been lost.

No significant changes have been made to the Realms world since this started occurring. So perhaps someone is doing something crazy on another Realms account that is hosted on the same system, and that's causing a cascade effect for me and other users?

This was not happening earlier today.

I did happen once a few days ago too though.
