Why isn't my sales channel app working properly on iPhone?

We are building a sales channel app but it is not showing the button to connect/disconnect in iPhone (safari and chrome). iOS 14.4

It is working as expected in desktop and android.

Please see screenshot for iOS and desktop

Desktop

iOS

As you can see, it says, no account connected and shop domain not found even though it is the same account

Tried to test on safari and I can see an error in the console. Not sure if this is related
