Error in ipad

[Ilan]

I'm getting the error:

Exception: 
Microsoft.JSInterop.JSException: this.mediaQueryList.addEventListener is not a function. (In 'this.mediaQueryList.addEventListener("change",this.onMediaChange)', 'this.mediaQueryList.addEventListener' is undefined)
value

On ipad.

Is there a fix for it?

Does this happen on other browsers? Does clearing the cache (and the other steps from this article) help?

Hi Martin,

I have the same problem, happening at a customer using Mobile Safari 12.1.

Already removed the 'defer' attribute and change the order.

    <script src="_content/Telerik.UI.for.Blazor/js/telerik-blazor.js"></script>
    <script src="_framework/blazor.server.js" autostart="false"></script>

I've attached the call stack, maybe it helps.
