UPDATE: I just tried to download something from the 3D warehouse so that I could capture the warning message and now it no longer shows the option to download into 2017 or 2018 and the warning I saw before is gone. It was there this morning right before I created this thread so they removed the ability to download into 2017 and 2018 formats in the last hour or so.
Is this the warning you mean? I didn't get this from the warehouse. It is from my saved docs.
The early bird gets the worm but its the second mouse that gets the cheese.
