In a APP, there is a H5 page, when the WeChat interface is called, the page appears blank and then transferred to the WeChat payment page. When I return to APP, the page is still white, and it will be displayed in a few minutes.

I studied it, when the WeChat interface was called, that moment, it had jumped to the WeChat page (the browser address was the domain name of WeChat), and the WeChat was calling its own interface, jumping to the WeChat to pay the page.
