Retailability Staging review for Shopify Subscriptions

I installed this app to try and see if I could move our company club subscriptions in house - I followed all the steps and couldn't even get the subscription option button to appear on the PDP. After looking into this I have found that the app is not compatible with third party payment gateways, and can only be used with the Native Shopify payment gateways - which are not supported in South Africa - essentially making this app unusable in South Africa.
