We have found that on several stores the wishlist page scrolls horizontally. This happens because the width of page container gets affected by the styles of the app as well as theme. We have designed a simple solution which fixes this issue.
1. Login to Merchant Console.
2.Browse to Configure Appearance => Wishlist page
3.On Wishlist page settings scroll down to bottom. You will see a checkbox “Prevent Horizontal Scroll on Wishlist page”. Enable it and Save the settings.
4. Reload the Wishlist page and the horizontal scroll shall disappear.
In case it still persists and you are unable to fix it using CSS, please contact us by raising a ticket.
