Several days ago, eBay Partner Network reported about an issue with EPN links. When someone clicks affiliate eBay link using Facebook app on iOS or Android, the click cannot be tracked.

The only thing is that workaround only works for iOS but not with Android.

We have already issued an update which will automatically append eBay links with appropriate parameter when they are posted to Facebook via your posting campaigns in RSS Ground.
No further action is required on your end!
We keep watching the situation around this issue and will keep our service in full accordance.
