Do any of the Android apps for lemmy display redgifs? I'm using liftoff but redgifs either have to be opened in the browser or don't seem to work at all for images.
You can use ImgurViewer along with any Lemmy Android app or browser. Set it to open Redgifs link by going to System Settings>Apps>ImgurViewer>Open by default>Add link
I'm using close to stock Android 12(LineageOS). If you're on a lower Android version, try tapping a Redgifs link from any app and select Always Open with ImgurViewer or something similar.
