I select all frame go to frame properties and change the frame rate, but just change the first frame
probably should be in the help section. Question when you’re selection are you dragging your mouse across the frames (another option is selecting the first and last frame while holding shift) or are you just selecting the layer and then pressing P? Beause I noticed if you just select the layer it looks like it highlights the cells/frames but it only has one showing up on properties.
this is what it should look like vs what it should’t look like
i’ll also add that there’s a function ‘constant frame rate’ in ‘frame’ menu. that changes duration of all frames in timeline.
