I was playing on my realm yesterday (gamertag Lindia57). All was fine. Beginning last night, I was unable to join my realm. Also, others cannot join either. I see "This may take a few moments" for about a minute, then "Unable to connect to realm". I've tried on my ipad via my home wireless, my iphone via cell data (which i've done before no problem), my win10 computer, and my kids accounts on their kindles. Same on all. Not sure if the world is corrupted? If so, are there backups that could be restored?

We're all running 0.15.6. I created a realm on one daughter's account and we can all join that one. It's just my realm that's got issues. Mojang support directed me to post online and enter a bug here.
