Android md theme not rendering main-view on phone

const app = new Vue({
    el: '#app',
    template: '<app/>',
    store: store,
    framework7: {
        id: 'io.framework7.testapp',
        name: 'Framework7',
        swipePanel: 'right',
        theme: 'md',
    }
}

When using theme ‘md’ on android phone the f7-view component doesn’t work, what would be the problem?
When I use the ‘ios’ theme it works fine!





        <f7-view id="main-view" url="/" main></f7-view>
    </div>
</template>

What F7 version, what Android version? Do you see any errors in browser console?
