When using the JS SDK client side integration, the checkout express page rendered won't scroll down. This is only reproducible on latested iOS 14.5.1. Android seems to work fine. Earlier version of iOS works fine. In fact not until couple of customers called custom support then we realized that for the latest iOS user Paypal won't work. You can try the following link as an example, must use iPhone and iOS 14.5.1 (latest).
Does anyone else have a similar issue??? NEED HELP, stuck for 24 hours!!
The modal pop up of the checkout page is not scrolling, the underline origin page is. Paypal need to add a Z-index to the modal or set overflow: scroll
I just checked a few other notable merchants' website using front end integration JS SDK, and also checked with another iPhone with 14.5.1. I can confirm there is an issue, prevent user from vertical scrolling. This is P1 bug.
