You can’t do it in the current Figma version. The best way to solve this is to use Fit Width option in the prototype viewer and have all of you app’s frames the exact same width. If they have different heights AND different witdths it will not work properly.

I would love to have this feature as well, previous post by OP, explain perfectly on the missing feature!

I’ve just found that “Responsive mode” in the prototype settings will lock the frames to the top, however it also locks to the left edge. Nevertheless, works better than frames bouncing all over based on the frame height.

you can just use state in prototype line.

Example : page A → Page B → Page A

page A

• navigate to page B


• use state at the bottom then click reset top position

page B

• navigate to page A


• then use state and click reset top position

it will works!
