Same issue here, it seems that there may be an issue on the epic server side as i can also only see the asset packs in my vault, not all purchased.
I’m able to update the packs in my vault, so there is a connection going on.
iv not downloaded the FAB plugin before so this is another thing i have no access to. due to this and the madness of having a website based system that doesn’t let you download directly, I’m completely locked out of all my purchased content!!!
Thousands of pounds and thousands of asset packs un accessible!
not sure how long the issue has been going on for as iv not needed to pull any new packs for a few weeks!
also tried full re installs, clearing caches and everything customer support had to offer. no luck!
