GIFs in featured image not working correctly

Hi there,

It’s because the “resized” image is no more an animated GIF, I’ll check whether we can figure a work around on theme level, but until then, I’d add the GIF to the post as an “full size” image, and then hide the Featured Image on “Full Content View” through Posts → Edit → Pen Options, that way WP doesn’t display the resized static version on mobile.

Thanks for your help. I have one more question. Why had the GIF animations previously been working on mobile featured images and then suddenly started glitching? They iOS FIs had been acting just like full-size animations and functioning normally.

Here’s an example of a glitchy one on a mobile device:

And a good one:
