@MojangSupport so are you ever going to fix the issues with realms, I mean it is a paid service yet it seems like it lowest on your priorities list seeing as the bug when editing the realms still exist and it's been a year already, can't replace maps without errors.

Unfortunately, it sounds like you might be seeing a known error: bit.ly/3uPUq8y bit.ly/3IHZq4T. We suggest upvoting this bug & adding a comment if you have any new info to provide. Also, feel free to review the bug report to see if any new updates. ^BT

That's not the error, it's literally just trying to go into the edit world settings and uploading the map only for the upload progress bar to be full and never actually complete, the bar is just frozen and the map won't upload to the realm.
