says Storage full when not

Hey, Midnight2905!

I'm sorry you're having issues with storage. There are many ways listed in the link below on how to free up more storage, but my #1 recommendation is to get an external hard drive that will allow you to have more space on your Xbox. I was constantly fighting
with my own storage problems until I finally got one and haven't had a single issue since. It was around $50, but I'm sure you can shop around to find what is best for you. There is some info on the storage link about hard drives as well.

You can find more information on Xbox storage here: https://support-origin.xbox.com/ms-MY/xbox-one/console/manage-storage

If you try the methods in the link above and still have problems, I would reach out directly to
Xbox Support.

Football Manager 23. It's an online save so I don't know if this affects it

Not yet, the game dev is saying that the console is the problem.

Hi, that’s really odd… it seems that is the game the one causing the problem

Did you tried the factory resetting thing?

This can be a bit odd, but maybe the message is related to the cloud saved.
May I know if you tried deleting unused cloud saved to see if that makes a difference? (Please note that this deletes all the saved progress and not the achievements on the selected games)

“On Home, select My games & apps.
Highlight the game, press the Menu  button on your controller, then select Manage game & add-ons.
Select the Saved data box, then choose the item you want to delete.”
