Following link from twitter in ios app to site doesn't display embeds in post

Using the default casper theme and iphone is up to date. The twitter app opens the link in what I assume is its own browser and displays a stripped down version of the site and the only embed that works is a standard website link. Youtube video’s, tweets and insta embed(using html) don’t show correctly.

Do i need to change a setting somewhere or is this normal?

No one else has experienced this? I’ve tested a couple of other themes and some have the same problem and some don’t. I assume this is a problem with Casper?
