How do I fix error code 0x808300003 or We can't save any more data for this game or app?

you have to delete save Files and choosing the option to do it both locally and in the cloud

But then my world will be deleted.

Thanks. Just tried this but still doesn t work. Game gets as far as syncing data and then the error code comes upmsaying something went wrong.

any ither suggestions?

Do you think it could be my data saved on my console that has corrupted? If so do you know how we could fix this?

Hey there SonicAce88.

Generally this issue pops up when you start reaching your cloud storage maximum. Cloud storage availability directly correlates with the amount of games you own on your Xbox One. Generally clearing past saves or the purchase of a new game should clear this
up. Have you also tried saving the game while disconnected from Xbox Live?

Hello there!

First, thank you so much for contacting us regarding your concern. I do look forward to resolving this problem together!

Can you try clearing your local saves?

To do this:

Select System

Head to settings

Select System

Then select storage.

Select Clear local saved games.

Select Yes to confirm.

Once your console restarts, try launching the game again.

Note: Clearing local saves will not affect your games as cloud saves will have all progress and will sync back.
