Firestick skip forward

Just noticed my FF and RR buttons don’t just skip 20 seconds anymore, they bring up thumbnails which are fine but seem to require pressing play. Am I wrong but didn’t those buttons just skip ahead and play with just the one button before? It’s fine now; maybe even better since you can see exactly where to skip to, but I don’t remember it this way before. Maybe I wasn’t generating thumbnails or something.

you will get thumbnails if recording is done, but only timeline if still doing active record
