Have someone watch you to see if the cassette is spinning & not engaging the hub, or if the chain is riding over the top of the rings/cogs.

You can look down and see if the chain is riding over the chain rings at least.
You are using 8 speed chain I presume. 7 & less speed is wider and may not fully seat between the cogs on the cassette.

You can check for stiff links.
Rotate crank backwards slowly.
Observe RDER.
It'll make a noticeable "twitch" if a stiff link passes through.
I see "some" rust spots on the chain. Maybe there's worse places?
IF the LBS has replaced cassette, chain & crank since Sept, I'd let THEM explain it.

IF they installed a new crank, definitely.
You haven't been "tweaking" any screws on the DER's have you?

Xie xie ni.
I'm sorry but you keep using acronyms without defining them. Where I come from, you use the full terminology, apply an acronym, and then you can subsequently use the acronym.
{ Presuming its not a well known, household, acronym like MPH }
"RDER ?
LBS - I infer to be Local Bike Shop."
Now you use "DER's" and assume I know what you are talking about. Sorry... No, I don't.
Yes, I know that I will have to go back to the Bike Shop but I wanted to get some research down so I could have some talking points to discuss the problem that has not been resolved to-date.
I have not tweaked anything. All I did was get the crank replaced on Sunday and go for a 3 mile loop test on Monday. Based upon the situation, I came here for some information from those who know more about bicycles than I.

There's like TWO other parts involved in the problem area.

DER = Derailleur, F = Front, R = Rear
LBS = Local bike shop
It may be a trick of the lens, but that does not look like a new cassette. It looks like excessive wear on gears 4 and 6, at least. Does the chain skip in all gears?

I think the paradox of
was too much for them. If they read that as a question instead of a statement, they totally missed the point.
You aren't where you come from.
