Site not displaying well on mobline when linked through messaging apps


Linking to my website through wechat message sent to others shows up a simplified view. Any idea whats causing this and how to have it display normally?

Located in China.

Before display it gives a message saying “please do not enter passwords, etc. on this site that is not part of wechat”.

Maybe it’s blocking scripts since it’s displaying through the messaging app’s in-app browser?
