Hey @Georges Al Nouar, welcome to Figma Forum and thanks for including the screenshot!
I tested this out on my end and I think I know what's happening — it looks like from your screenshot the playback is set to play once. To get the ping-pong effect, you'll need to click the Playback button twice so that it looks like this, showing the ping-pong effect is in play:
Please let me know if this helps you move forward, or share a bit more about the steps leading up to the unexpected behavior and I'll be happy to take a deeper look and flag this with the team if needed.
Hmm, that definitely shouldn't be happening. I just tested this out again on my end on both the Figma Desktop App and a browser (Chrome), and the button worked as expected.
So that I can share more details with the product team, can you reply with the following:
Is this happening for you in the browser and Figma Desktop App? If so, can you confirm that there are no pending updates?
Is this happening with only one or multiple files? This will help us determine if it's file-specific.
What type of device and operating system are you using? Does this happen if you try it on a different computer?
Thanks again for confirming those details and helping me rule out those potential factors, @Georges Al Nouar. The next step is to take a closer look at a file where this is happening. I’ve sent you an email with instructions on how to share access securely.
