Maybe my question is fallout from legacy P3D project only able to be open in one version of Plant. According to this "In The Pipes" chart, it looks like this may no longer be the case? Specifically, we have a project that I thought was 18, I have drawings checked out through collaboration in 18, but someone else in my group thought it was 19 and could see my checked out drawings. Anyone else noticed this? My XML version is 92.
