Has anyone lost 15-20 pounds, but not seen any difference?

I’ve heard of people not losing and seeing differences, but on the scale I’ve lost almost 20 pounds and I don’t notice my clothes fitting different or a difference at all in my progress photos. I haven’t done measurements, and I may start, but I wondered if anyone has lost and just not seen results anywhere else.
