Prototypes for me have started showing a blank/empty screen when using content scales like "Fit width", "Responsive", or "Actual size (100%)". Only "Fit width and height" renders correctly.
I found a workaround with Claude. I was using a fill on my Frame which I have always used so the background isn’t blank
Removing fill from the frame fixes the prototype rendering. However this causes the prototype background color to show through where frame content doesn't reach.
Prototype with Frame Fill
Prototype without Frame Fill
