Webview isn't shown in sitemap if SSL/https is used

I’m running OH 2.4 stable version with some webview objects to display Grafana graphs or TimeLine embedded in the sitemap using https.

Everything is working fine via WebGUI, however in IOS App the embedded Webview objects are not shown - I just see a white frame.
I tried different approaches using a static html or direct URL, but always the same.

Webview icon=none height=6 url=""

Webview icon=none height=6 url=""

When using http instead of https everything is working in IOS App as well.
I already set “Ignore SSL Certificate” to ON but without any change.

Is there anything I need to change in sitemap or IOS app to make it work?

many thanks :slight_smile:
