Valvebody issues?
You can get a benz scanner, someting like carly app for benz and see if there any codes stored for the trans.
Doing a fluid and filter change isnt a bad idea and isnt that bad of a job either.
if you have a S with LSD, doing a rear diff fluid change while you are at it is good aswell.

Fluid change can not hurt

Took it to the dealer and they changed the solenoids.
Car is 2016 as well and now has 65,000 km or 40,000 miles =D
If you are planning on keeping the car, like I am, get the extended warranty.

Now, i own xentry system.
I can tell you, the adaptation reset is totally different by using xentry.
Also, you can use xentry to re-adapt.
It has upshift, downshift, and acceleration downshift adaptation program.

But thank you all for the ideas, ive decided to first take it to the dealer and go from there. Will make further updates.
Visited the dealer and they performed an adaptations reset. Initially after the reset the car was shifting worse but the dealer said it would do that for the first little while. However after 200 miles the shifting has improved "less jerky" but the transmission is still holding the gears for too long. Planning on giving it some more time then go for round 2.

I took the car to the dealer again and was told by the SA that i needed to drive 2k miles after the adaptations reset, and was told that only after that 2k mile window theyd be able to start looking deeper in to the issues, such as dropping the pan and checking out the selenoids. Ok 2000+ miles pass and i still have the exact same issues, take it back and the dealer still cant help me, they said everything is within spec on their computer and they cant do anything about it. Lol what?
Total waste of time and energy, time to switch dealers.

Have to be specific with Benz, its not an adaptations "reset" you want which xentry mentions this wont help shift quality but you want to "perform adaptation" and under this, you will perform adaptation for the Wet start up clutch, upshifts, downshifts and accelration downshifts. So you want all 4 to be done.. Adaptations performed on these, not to reset adaptions which is when a component is changed.
Going down the tree of things to do for MCT issues,
Fluid and filter change,
check trans mount
Software update
Full adaptations
If all else fails, time to clean the solenoids and or replace, which isnt much of a big job anyways.

Transmount is fine.
Software was updated to latest at the first visit.
By adaptation reset i meant they re adapted via xentry. Xentry>Adaptations>Adaptation of the gear shifts>upshifts 1-2, 2-3, 3-4, 4-5, 5-6, 6-7>downshifts and so on.
Then they said it will further adapt to MY driving style in the next 2000 miles, which it did and the trans did become more responsive to my driving habits. But it didnt fix the issues i was complaning about. I believe they need to replace the selenoids on the tcu which i mentioned to the dealer but it was ignored.
And for the transmission fluid change, dealer should do it out of their end. The car is still under factory warranty +3 years of cpo. So if thats one of the remedies then i dont see why i should pay for a premature trans fluid change.

These service advisors and techs dont see enough of these cars and issues to be very knowledgable with them, that is usually why they either shotgun the problem and throw parts at it, or consider it normal to get you out the door.
There are good techs out there, they are rare.
Trans fluid is to be changed at 4 yrs or 40K miles, whichever comes first..
Mercedes benz of manhattan, failed to change my brothers rear diff oil at the 2,000 mile break in interval when it was brought into service... they told me its the customers responsiblity to pay and ask for certain maintenance items to be done. Lol. There is no winning with them.
You seem to be on the right track for sure. I would say solenoids must be next as you mentioned for sure.
