Hello, We have noticed issues in IOS Safari >16.4 versions page caching (during browser forward and back navigation, also called bfcache). During back-forward navigation when the page is retrieved from cache we receive an error (via window.addEventListener('error'). This error returns very generic information around it: message: Script error. source: lineno: 0 colno: 0 error: null As mentioned, issue emerged from 16.4 version and ONLY in IOS devices.
