I would so switch to ARCSite if it weren't so crazy expensive! It's really the best iPad CAD app out there, and I'd subscribe in a second if its cost were reasonably comparable to AutoCAD and others at about $50 per year. Even their gutted version (no dwg) is more than double at $120 / year! They probably could do a version with no photo markup or embedding, since I can do those in other apps and don't need them for CAD. That's not going to happen, alas - just read the ARCSite reviews about being too expensive and their responses.
I doubt Autodesk reads this forum for feedback. I think they put it here so we feel empowered even though nothing we say matters, or they would have restored the usable version until they got their stuff together.
I doubt Autodesk sees this as damaging their brand, but after this fiasco I'm done with their entire company. As far as using Autodesk again, they've proven that they'll put idiots in charge of an app who have no clue as to their users' needs (just read the last paragraph of the Developer Comments in the app store reviews, where they basically admit they're clueless!). And worse, they won't admit they're wrong and restore a working version. Just more mocking gibberish about how great the app will be... someday... later... whenever... over the rainbow (as they shamelessly keep our subscription money).
They just did an update (December 10th or so, 2019). Why? It's just as broken as the previous version! Did anyone at AutoDesk lose their job over this? Probably not, and I bet they'll all get bonuses!
Too bad that Apple keeps posting year-old reviews at the top of the page, default sort order in their greedy effort to sell this POS! The reviews were accurate then, but no longer!
You're right about the only current solution. Everyone who found a fix jumped to a different app because THERE IS NO FIX (not yet, maybe never).
But we're still mad and posting because everyone who got screwed by this POS DESERVES A REFUND!
