Hei I just run into the same issue as well.
If I set up my Mac location to be “Application Data”, the path according to the Offers Cloud Save page should be “~/Library/Application Support/GAME/{EpicID}/”. However, the actual save files are synced into “~/Library/Application Support/Epic/GAME/{EpicID}/”.
It would be nice if the cloud saves would be synced into the folder that is shown on the Offers page or adapt the example for “Application Data” to indicate that it corresponds to “~/Library/Application Support/Epic/”.
