Nope- this isn’t just limited to the Lite version.
I just finished a round tripped half hour project from Premiere CS6->Resolve 9.1 via FCP XML->Premiere and no matter what I did, Resolve forced the conform to a 24fps timeline.
We shot 4K R3D at 23.976 and worked on a Premiere sequence with those exact settings.
I verified that the 23.976 flags in the exported FCP XML were correct True
Prior to the import, master settings were set to 23.976 playback and the 23.976 R3D clips were brought into the Resolve media pool under those settings, and clip info confirmed that Resolve read them as 23.976
On the conform page, I imported the FCP XML and was met with a window warning me that the imported sequence had a different fps than the project settings.
This is bad because the 23.976 offline video would not link to the grade, and I missed a deadline trying to trouble shoot drifting audio back in Premiere.
The only solution was to go ahead and render out to true 24fps and then bring the video back into Premiere and right click the MOV in the bin->source settings->force frame rate to 23.976
