Here are a couple shots showing all the oil.

I have been chasing down a similar problem in my 981 Clubsport all season. The transmission is the same between cars (maybe it is a different P/N but it is the same). I also have had the pan and a half shaft bearing seal replaced. It still leaks. It seems to be coming from a port on the transmission that should not be leaking. The problem is that when it pukes some oil it gets everywhere so it is really hard to track down. The leading theory on mine is a bad differential seal which is repairable but requires pulling the diff but it is not a trans out repair. I'll probably be doing that next. If you are in warranty, they will likely just replace the transmission before trying the differential seal route. Let us know if you solve it. It might help me track down my issue.

I'm surprised this isn't more talked about since goes back to the 981. You'd think they would have found and fixed the issue by now.

PDKs are fairly complex with lots of sensors, solenoids and seals that can fail. They are very repairable but Porsche just replaces them so there are not a lot of PDK experts out there.
I don't think these issues are that common but they are amplified by hard track driving.

Well remember, there was no street GT4 PDK with the 981 so not so many data points. And Clubsports are racecars so all driven hard. Racecars break stuff and teams just fix it.

It's great having info from people like you with Clubsports since they'll get more abuse than any street car.

Mine is also leaking and I need to get it to the dealership to get it checked out. I also had my right side inner CV joint bolts come loose spraying CV grease everywhere. :-( I retorqued the bolts myself so it could still be driven, but will need that looked at as well.

That's an easy fix. It's the O -rings on the cooler lines. Mine had it done and it fixed the problem. Clean/degrease that area and see if it is coming from the hose connection. It looks like it is.
edit: BTW my dealer told me I needed a $25k new PDK. Indy fixed it for $800.
