Hey ​@YGor, thanks for reaching out! I understand how frustrating this can be. Right now, it’s not possible to connect a prototype interaction directly to another page in Figma.

Could you share what kind of interaction you’ve set up in prototype mode? A screenshot would be really helpful in understanding your setup.

In the meantime, I came across a workaround that might help! You can check it out here: https://www.youtube.com/watch?v=HKdZKasqm4g.

Let me know if you have any questions!

Thanks for your answer. 
Given this feature is not available, I work now on the same page and animate between frames. 
With a detailed prototype, packed with objects, frames and animations, it’s more difficult to work. Everything looks like a big mess, so pages can make it more simple.

Thanks again
