I mean the phone i think is a 10 the software says 15.4.1 ?
Oh, I see, you mean you have iPhone X and the IOS version is 15.4.1.
I checked that the latest Metamask version for iPhone is v5.1.0, have you updated it to the latest version? And how do you connect PancakeSwap to Metamask? Did you use the Metamask browser feature?
