Hi @Ashok ,
I am using the Ulitmate branding plugin to rename this area. (Checkout - Shipping stage)
While its working for most area's e.g.
Shipping >> Confirm email
Enter Your Checkout Information >> Enter Your Checkout Information
For some reason this one is not working ???
Please enter your shipping information in the form below to proceed with your order >> Please confirm your email address to proceed with this booking.
Could you please take a look into why that one is not taking effect?
