After submitting the Shopify public app for review, I got the following issue from Shopify’s end:
Don’t use pop-up windows or new tabs/windows for essential app functionality like running OAuth or approving app charges. This protects the functionality of your app from being compromised by pop-up blockers.
I am using Shopify’s billing API i.e. recurrent and Usage based API. As soon as customers click on Accept for billing, Shopify takes them to new tab, which is by default. Can anyone guide me on how to resolve this issue as I need to re-submit my app for approval asap.
