Popup not working on phone

We have a pop-up that opens when someone hits the page… On that page is a link to a video that plays… this works fine… This issue is when opening the page from a phone the pop-up does not show the close button in portrait mode… if you turn the phone to landscape the button then shows… please let me know if there is a workaround or fix coming…

Are you using a modal or card modal?

See for regular modal.
