I checked that app’s source code, and basically they’re doing their own avif decode call instead of relying on a browser/webview to handle it. So essentially they forgot/don’t know/don’t intend to implement animated avif. Looks like they also use the aom reference decoder instead of using something faster like dav1d.
Your demonstration is a sluggishly loading static image on my end, so I guess support isnt that widespread :P
(Im using the app “Summit”)
