React native web+H5 is very stuck.

the bosses react native web+H5 is very slow, android can"t even click on the switch, and iOS is also very stuck. Is this a normal phenomenon or is there a problem with the code writing? If it is a normal phenomenon, we have a second solution is to bridge the native WebView, but if the bridging native webview is encapsulated by rn calls, then iOS can load the page, but android cannot load the page. If I set a background color for webview, we can see that the background color is displayed first and then a blank screen is displayed. What is the reason for this?
