I am using RazorPay gateway in my Laravel project where razorpay works fine in normal browser like in Chrome, Opera, etc.
But when it comes to mobile app like instagram where it provides in-app browser. When we click on link on instagram it opens its browser in app where razorpay payment is not working.
In debit card section, it asks all the required information like card number, expiry date, CVV and after this page gets blank. That banks OTP page is not loading.
After struggling a lot I found the solution.
Just add this line to <head> tag
<meta name="mobile-web-app-capable" content="yes">
Everything works fine
