I tried it again recently. The mobile app is just too slow to start, and I'm currently stuck with a phone with too little memory to not autokill stuff. I realize Chrome's apparent snappiness is probably due to some questionable and likely anti-competitive integrations by Google, like Microsoft in the 2000s.
+1 It's trivially easy to stop ALL media from autoplaying - including gifs! It's wonderful (but sometimes jarring when I expect a gif to be playing already)
