Problem with SplitViewFrame on IOS

Hi,

We used AppLayout with Vaadin version 14.2. We have a problem with SplitViewFrame on IOS/IPhone devices (tested on IPhone 6, IPhone 8, IPhone 11). The SplitViewFrame when shown on iphone device the header is displayed under the navbar of the applayout. I attached a screenshot.

Everything works fine on Android phones.

On the other hand, The business app’s SplitViewFrame works fine on all devices. But it does not use AppLayout. Is this a problem with AppLayout component? Should we abandon applayout component?

Best regards
