[SOLVED]Help with Restore Purchase block

My post is related to IAP on iOA / Android (choose one or both)

I have read through the available IAP documents and am struggling to understand or use the content on the following page to help me with my issue.

What I am trying to do is:
I have set up in app purchase on my app and it works successfully, however when they want to restore purchase, it doesn’t work. It just shows a blank page.

What I have tried so far is:
This is a screenshot of the block i used for the restore purchase

Any help will be appreciated.
