Our twitter cards were approved last month and everything seems to be fine in desktop browsers but the same cards works differently in mobile devices. One issue which what we have found is for videos, thumbnail is not being shown in mobile devices for player cards. In preview tool it works perfectly as it is for desktop browser. can anyone let me know what is the issue in this?
P.S: can you guys provide a preview tool for mobile devices, this would save a lot of time. since only way we can test twitter cards in mobile devices is by testing in production environment which is not a good practice.
