We have created a 50% discount coupon but it's not getting applied to the subscription price.

Also, we notice that though we select the USD pricelist initially system shows the price as $<INR Price> and after a few backs and forths USD price is shown.

Also, we noticed that the import of USD price list is not permitted. And also, the import of subscriptions is not permitted. Why?

Also, the import of plans, add-ons, and coupon keeps on giving errors, though there is no error. It is unable to give the exact cause of the error.
