IAPHUB Paywall not showing products in testflight

Hi There,

I don’t know if this is the forum to post this in but I have been using the premade paywall and when on testflight it says no products for sale. I have created products on apple and IAPHub so I’m not sure what to do. I’ve gone through the forums and help documents to no success. Is there some part of the paywall that I have to link to the specific paygroup because how else will it know.
