I'm new to Figma, just started learning it today, so maybe I'm missing something obvious.
I have a frame with a design that uses constraints to scale nicely to different screen widths. When I manually resize the frame, I can see the content align correctly. But when I preview it using Prototype on different devices, it seems to use the frame's initial size instead of fitting the device screen. So that the frame can be either too wide or too narrow depending on the device. Is there a way to make the frame width fit automatically?
