Iframe doesn't work in IOS

Good afternoon, I am new to this subject.

I created an ionic app using iframe. The same loads a woocommerce website. on android it works perfectly but on IOS whenever I add a product to the shopping cart it is not assumed that product, getting empty.

It works, android and all other browsers, it doesn’t just work on IOS.

this was the code used:
< ion-content [fullscreen]=“true” overflow-scroll=“true” >
< div style=“width: 100%; height: 100%;”>
< iframe style=“width: 100%; height: 100%;” src=“https…” frameborder=“0” >
< /iframe >

I also added this code in the config.xml
< allow-navigation href="*" / >

If you can help me, I’ll be grateful
