Android in app purchases broke from UE5.2 to 5.4

In app purchases were working flawlessly in UE5.2 using the following blueprint.

However in 5.4, i cant get them to work. I tried both start in app purchase As well as make an in app purchase (red and blue):

However the payment dialogue doesn’t show and the on failure node fires.

I need a professional to help find the problem urgently and willing to pay anyone who helps me diagnose the problem.
