Server space costs money and users of Make and old Pro versions aren’t doing anything to help with those costs. Not a far flung or disjointed thing at all. The Collada version has been offered to users for more than a decade. ( I would expect them to drop support for SketchUp 2019 within the next month or so although that’s only a guess.) That saves server space because they don’t need to convert and store uploaded components and models for a whole bunch of SketchUp versions.
They did delay dropping support for 20 until last year but I imagine COVID had something to do with that.
The 3D Warehouse has normally only supported the current and previous two versions of SketchUp for years. I wonder how people are expected to know about Collada? This seems another example of Sketchup/Trimbe being very far flung and disjointed.
