We are using Paytm extension in our client's website https://www.safaribags.com which builds on Magento 2.1
When customers click on "Pay with Paytm" button, the customer redirects to the Paytm Pay URL. On the Paytm Pay URL, browser's back button is enabled, so when they click on that button, they redirect to the website but their cart would be empty every time.
So I want to know some solution for this issue.
This issue is in the live website, so please support ASAP.
