reporting your Trip was acting up.
Chances are it would have anyway, but..., well, maybe not.
The Tip fluid doesn't suffer from contamination like the engine oil does so the only thngs that affect the Tip fluid would be a build up of wear particles (which are probably mostly removed/trapped by the filter) and some degradation of the oil's additive package.
Chances are it would have anyway, but..., well, maybe not
I'm kind of on the fence on this. On one hand I'm a proponent of more frequent fluid changes. OTOH if something did go wrong...
My info from talking to various Porsche service managers is that a delayed fluid change is about as bad as no fluid change. That is if a Tip is run too long on the original fluid that a fluid change seems to accelerate the Tip's demise though there is really no way of knowing this is true or not. The word I get is that it seems to be quite common an overdue for a fluid change Tip is brought in and the fluid changed and then not too much time passes before the car's back with a sick Tip.
Now one thing to consider is that often times what prompts a Tip fluid service -- especially if one is overdue! -- is the Tip is acting up already. The thinking is just a fluid change is needed. Were I the owner of a Tip equipped car and it started acting up I'd probably 'throw' a fluid service at the thing just in case, though I believe I would have treated to more frequent fluid/filter services than the manual calls for.
Consider this: The Tip fluid doesn't suffer from contamination like the engine oil does so the only thngs that affect the Tip fluid would be a build up of wear particles (which are probably mostly removed/trapped by the filter) and some degradation of the oil's additive package.
Now wear particles build up is primarily a factor of how much the car is driven, the distance it is driven.
Additive package degradation... Due to the very low exposure to contamination I would hazard a guess the primary factor is also the distance the car is driven.
So, this is what I would suggest: Consult your car's owners manual and see if there is a time callout for a Tip fluid change. If there is and if that time has expired or is about to, change the fluid/filter. If there is no callout on time (or the time has not expired), if the change is based on distance traveled and your car ain't there yet, don't have the Tip fluid/filter serviced.
If you want some reassurance on this you might consult with your local Porsche dealer service department and see if Porsche has published a modification to the Tip fluid service schedule. Sometimes Porsche does this and if so you want to know.
Not to sway you, but were the car mine, I'd be seriously tempted -- unless my research into this found it ill-advised -- to have it done just to reduce the amount of particulate matter in the fluid (not all the fluid is removed during a fluid service) and have the old filter replaced with a new one.
Along with these positives (though hard to quantify) the fluid change would refresh the Tip fluid's additive package. But it is not my car. It is your car, obviously. And your decision.

Anyhow, along with these positives (though hard to quantify) of the reduction in particulate matter and a new fresh filter, the fluid change would refresh the Tip fluid's additive package. But it is not my car. It is your car, obviously. And your decision. And probably made more difficult by the wishy-washy above. Sorry.
