above is how it behaves for finished games. I tried again with an in-progress game (48 hrs per move) and it says "generating GIF" but just sits there with the blinking cursor (extending periods). Tried two different browsers with this too
Animated GIF share option not working

We have been working on this for a few days now. By chance does it only not work for live games for you?

in-progress games, it says "generating gif" and looks like it's doing something in the background but it never finishes.....

This one's over:
https://www.chess.com/live/game/2343656050
and this one's in progress:
https://www.chess.com/daily/game/175780342
see how the in-progress one acts like it's generating it but never does? Firefox & Chrome are both doing the same thing on both win10 & win7

I did finally get the one to complete... but it took ages I am really sorry for the trouble.
We are working on this!

No problem! It's just a fun/easy way to share a game every once in a while. Please update when it's good!
On my profile page there is a category called points. I have one point. How did I acquire this point? How would I get more? I assume it is a good thing to have a lot of points

got one to work - took a while but it finally kicked it out:

Where does the gif go when created? Does it say finished and give you an option to save it? What browser are you using?

seems to be working fine, other taking 15+ minutes to make it:

Can't get it to even try to make the GIF with this 15|10 game:
https://www.chess.com/live/game/2343656050
this daily game generates the GIF in a split-second:

I just checked an in-progress daily (48 hour per move) game & it's not fast.
Is anyone else having trouble with the animated GIF option not working? I click on the share icon, then a little timeline-bar scrolls, then nothing. The "current image" share option is working as expected.
I've tried a couple different browsers - same result.
