It looks like every Dragon at least since CRS-3, every Cygnus, and even the last HTV carried cubesats to ISS. These days it would be unusual not to carry any.
And this IDA is the 2nd unit built, correct? With a 3rd in production?

They've had an interesting traffic pattern of late with up to six spacecraft attached.
...Delay is IDA payload and IDA EVA crew related, as the crew meant that was meant to install the destroyed IDA 1 is no longer on orbit and the new crew that is to fly on Soyuz MS(-01) received IDA-2 specific training in NBL for the entire set of planned and contingency EVA's. The current crews onboard due not have the IDA installation and contingency ground training the Next crew received. The onboard crews have a big deficit in IDA training that the next crew doesn't.

The onboard crews have a big deficit in IDA training that the next crew doesn't.Sometimes I think they really make this harder than it needs to be. Yes, the training is important...but is putting the IDA on with a computer-controlled robot arm, especially when simulation (even on orbit) is very advanced, really that hard? Especially when virtually every move is prescripted and monitored fromthe ground? And the IDA 1 crew could sit in mission control and provide verbal "astronaut eyes" assistance to ISS?NASA will never get to MARS this way.
Has more to do with training for contingencies than training for "everything goes right so all they have to do is stick it on a robot arm"There are likely failure modes that could require a contingency EVA. EVAs are dangerous, you don't want to be out there longer than you have to. You want those performing EVA functions to have practiced them in the pool before asking them to do it the first time in orbit.
Got it...but what sort of contingency requires an emergency EVA when installing the IDA? Is there actually nowhere to store it until the trained crew arrives a month later?

The only place to store it is in the operational location or the Dragon.
Dextre... Here, hang to to this for a bit...
