Installed a complete group set for the first time.. 11 speed Campa Chorus group on my bike. All seems pretty fine apart from the smallest cog, this keeps skipping the chain. Any ideas what could be wrong or how to fix this?
Chain skipping on the smallest cog

Is every component (chain and cassette) new? Did you size the chain? Are there stiff links in the chain? If you pedal backwards slowly does this happen?
Edit – did you adjust the high limit screw?
Release the cable, does it still skip?
Check the limit screw for the high gear (smallest sprocket). Maybe a bit too far in?
Looks like your chain is too long
Just jumps on the higher gear.
