Can't import gif from After Effects to photoshop

Hi everyone! 

I having trouble importing a Gif I did on After Effects, to photoshop.

I’m using a macOS Big Sur 11.5.2 and Photoshop 2021

1. I exported the gif from AE with all necessary definitions + png sequence
2. But when importing into Photoshop, it is not possible to place the animated gif on the timeline. When I click on the buttons, that circle icon with the dash appears (locked). It looks like the entire animation is just a single frame.
3. I tried also do export ‘Save for web’, to see if it worked. So I clicked on the play button and it recognises that there are 75 frames but it only appears the first one. 
4. Even after it’s saved as a gif, it only appears the first frame.

Thank you 🙂
