The animations really help you understand your opponents move in 1 minute games so they serve a real purpose and the app user experience is worse without them.
I found a way how to enable animation again. Just go to the settings, and set up animation mode to "arcade". Another one will not work, but that one works almost the same as before.
p.s I tried this one only on PC, but hopefully, it may be working on iOS too
Please bring the animations back.
