The widget is cut off or has empty space

The widget resizes itself through the small script included in the Install code. If you pasted only the frame, or your platform removed the script, the frame keeps its starting height.

Fixes, in order: - Copy the embed code from Share again and paste all of it, including the script line. - If scripts are not allowed, set a fixed height on the frame (for example style="height:620px") and adjust until nothing is cut off. - If the widget looks right on desktop but is cut off on phones, the same fixed height is the cause; auto-height solves both.
