Cant upload worlds to realms

I keep getting “Failed to find to upload your world” and " an error has occured” message when trying to upload my world to realms. I’ve tried every method. Reset device, uninstall and reinstall, changed networks, tried on 4 differnet devices ( 2 phones, tablet and xbox s/x) I even bought 2 sperate realms and nothing is working. Please help I've been a paying customer for years. I’ve spent hundreds of dollars on this game. Ive already lost a few worlds to this same issue i cant be the only one going through this.
