Suggestion for the cloud system to minimize issues

Could the cloud function be determined by the user rather than enabling and disabling the function?

Say a button to sync with the cloud and another to download.

Cloud settings that are enabled by default can cause weirdness, because if your offline and change a setting the cloud may change those settings to what it was before;

Or fail to sync if the server is down for whatever reason.

Choosing when to sync and download makes it clear to the player what will happen to their settings rather than some mystery guess work as to if the settings are uploaded or download.
