Cant delete game data

your worlds will delete if you delete your data but if you uninstall the game everything will still be saved on your Cloud-save...you would have to go to game info and manage your game data manually to delete you worlds but that cant happen if you uninstall
the game

No, you cant delete or parcial delete any save data

As of now i am locked out on both systems. I cant move the data or delete it from the 360 it says "items on another xbox are waiting to be uploaded" Then i go to the xbox one and try to run the game and it says the same error. I have gone back and forth
a few times. I also started a new game on the 360 and saved it on the hard drive. I then moved this data to the cloud, overriding the cloud saved data, and then went back to the xbox one again and got the same error. Also because you cant delete the cloud
saved data i cant start a new game on the xbox one or select a save device without getting that error.

i have even tried install a new windows 10, but the game still cant launch after sync my data. I switch to another new microsoft account and launch the game with no problem, seems there have some problem on my save data on cloud and when the data load it just cant load into game. i cannot find any method to delete my cloud save

Have you tried deleting all data for the game, as when i had Need For Speed Most Wanted, i had the exact same problem, and when i removed the data from the first time i put it in, it worked fine, and i found out that the data corrupted somehow. I suggest
(If you have any) deleting any data that you have for the game, and then retrying it. If it does not work, then im sorry, i cant help any further.
