Created attachment 417613 [details] Demonstration of the events not firing as expected Have isolated the problem and can be seen here: https://lucid-shaw-b293da.netlify.app/ In WebView browser: 1. Navigate to Page 1 2. You should see the console.log “onpageshow - page 1, load” 3. Navigate to Page 2 4. You should see the console.log “onpageshow - page 2, load” 5. Use the back button and you should see the console.log “onpageshow - page 1, load” 6. Go back and forth between Page 1 and 2 and the console logs intermittently do not fire The expected behavior is that the onpageshow and onpagehide to fire every time but the events do not always fire when navigating backwards to a cached page
