Snapping not working properly

Hello there!

I have recently switched to Rhino 8 but I keep on having trouble with OSnap - it is only working when selected line/polyline has points on. Is it possible that it is trouble in settings?

I have already tried to check OSnap setting - non of the combination is working, I have tried to put it back to default settings, still no luck.

Is there anyone with an advice, please?

Thank you!

Hi Adam - is this true of all snaps or just some?
