Hello! I'm having problems with WebView, can anyone help me?

My webview is showing a small black frame when trying to load a site, I’ve changed the link several times thinking it could have been my site, but it still stayed the same. Check the screenshot I took below.

Just below to see what I left as default, I just added the Link to be loader but only a red frame appears in the rendering and not the page I put.

It seems like you’re viewing the web version of your app. If this is the case, then nothing is wrong. The web-view, unfortunately, is currently only supported on mobile.
