Very much an issue, so much of an issue that I am telling friends not to buy the Series X if they don’t have to. If I could go back to the Xbox One I would. Bought a brand new Series X and with nothing but Minecraft on it I was told I had insufficient space to save my worlds. I fail to understand how I was able to play Minecraft with 45 worlds on the Xbox One and multiple other games but am unable to even load my Minecraft worlds at all. I returned the first Xbox Series X (thinking it was an issue with the console) and am still having the same issues with the new one. I have tried every support option but none have worked. I have even deleted 30 of my worlds in an effort to reduce cloud space but this has not worked either. PLEASE HELP resolve this issue.
I am having same issue on Xbox series X. I was able to plat 45 worlds on Xbox One with no problems but unfortunately it died, and I had to get the Series X. I have deleted 29 of my worlds and am down to 16 but still am unable to play. I even bought a different Series X hoping that the console was the issue.
It is a bug that has been being reported for several years and has been closed and reopened. it is merged in issue # MCPE-162920. it occurs on many platforms and seems to be a cloud error not a console or Minecraft problem. My Minecraft world is less than 400 Mbps and won’t save and I only have Minecraft on my Xbox Series X console
