[CRITICAL] In-Island Transactions - Items not granted after purchase since latest update

Summary

In-island transactions are working (V-Bucks are spent) but purchased items are not granted to players. Players spend V-Bucks for nothing. This worked perfectly for 3 months and broke after the latest Epic update.
Issue occurs ONLY in public/private version but NOT IN UEFN SESSION

Additional Notes

Player keep getting scammed now since last week because they don’t receive what they purchased. I hope Epic will quickly find a fix

I already created miltiples versions after Epic update, it has changed nothing.
I already sent a ticket through Epic Assistance but it seems they don’t like to understand what im explaining.
