I'm using javascript api version 4.13. My popup is not showing the content when application is viewed on a mobile device (ios and android). It works fine on a desktop. I used the developer tools in Chrome to look at the html and css. I attached two files that show what the popup content looks like on the desktop and mobile device. I believe there is a media query somewhere but I don't know where to find it. I tried the following but it did not work:
.esri-view-width-xsmall .esri-popup__content,
.esri-view-width-small .esri-popup__content {
display: flex;
}
