MobilePortrait layout type doesn't work when embedding a report

[KoenC]

The used configuration.
{
    type: 'report',
    id: report_id,
    pageName: page_id,
    embedUrl: 'https://app.powerbi.com/reportEmbed',
    tokenType: models.TokenType.Aad,
    accessToken: token,
    filters: filters,
    permissions: models.Permissions.Read,
    settings: {
        filterPaneEnabled: false,
        navContentPaneEnabled: false,
        background: models.BackgroundType.Transparent,
        layoutType: models.LayoutType.MobilePortrait
    }
};

The iframe src attribute gets the parameter 'isMobile=true', so the configuration is parsed correctly.
No javascript errors are thrown.

But the report is still shown with the 'Master' layout type.

I dont know if this will help you now, I was stuck on this today and found the solution as follows:

{
    type: 'report',
    id: report_id,
    pageName: page_id,
    embedUrl: 'https://app.powerbi.com/reportEmbed',
    tokenType: models.TokenType.Aad,
    accessToken: token,
    filters: filters,
    permissions: models.Permissions.Read,
    settings: {
        filterPaneEnabled: false,
        navContentPaneEnabled: false,
        layoutType: 2
    }
};

Changing the layoutType to 2 will render it in mobile portrait mode, give it a try should solve your problem.

You do not require any additional paramaters in embed url for mobile view
