Symptoms
- The website renders on a regular Android device but not on Meta Quest.
- Your project is using 3D WebView for Android.
Cause
3D WebView for Android is powered by the Android System WebView, and Meta Quest uses an outdated version of the System WebView (currently Chromium 91 from 2021). So, some sites that use the latest JavaScript features may not work in the System WebView on Meta Quest.
Resolution
First, I recommend using remote debugging to check the JavaScript console for errors. This should help indicate the issue that's preventing the page from rendering (e.g. a missing JavaScript feature).
If it's your own website, you can use the information from step #1 to update the website to make it compatible with the Meta Quests's old System WebView. Or if it is a third party website you can't update, an alternative is to switch to 3D WebView for Android with Gecko Engine, which uses a more recent browser engine.
