Hey @dimitrie!
I think that’s been exactly the problem in the initial post … and it seems to apply for any IFC uploads (not just my specific files).
So I guess, your suggested solution to use the IFC’s GUID value for the applicationID during the IFC upload seems to be the most logic conclusion to be able to provide an applicationId (anyways) (maybe in addition to the current data.GlobalId). … And doing so the version comparison should work the regular way also for IFCs, right?
If I’m not mistaken, the IFC upload’s behaviour regarding that hasn’t changed since then.
That’s why I wanted to just quickly bring that to attention again.
