After update the pmdg 737-800 (bought on the pdmg site not marketplace) i copied the plane from the community folder where it housed since installed, i copied to the 2nd pc msfs ( which have different xbox account) to it community folder and works fine.(same goes for the Pdmg’s dc6)
I think it does not work with marketplace version.
Which was in my case with carenaro c182 rg this i bought on marketplace and had to buy a second copy for the 2nd pc
For the fenix i do not know.
But ive noticed when i got redwings citroën fantomas (it was for free to get on simmarket) this did not worked because it was located in the official folder
It had to be intalled by simmarkets own dowload and install app. (I quess it has to do to prevent to copy) wonder also if this have something to do with upcomming 2024 version.
So far this hold me from buying L1049 which seems an awesome plane to me
For concearning weather according live this is overall and if from/on the same server say europe west, this should be working as similair with same type of clouds and winds it uses the same data in the same timeframe so data transfer through wideview should hold up as such.
Hint
If you experience stutter through wideview (i mean on the second pc client compared to 1st pc ) consider to run yourcontrols/shared cockpit next to it (i have good results with it).
