I suspect it relies on some external tools and packages. Since the A/R tool is also part of SU for ipad, I’m not surprised it’s fully functional on iOS. I guess the package isn’t compatible with some android releases ?
the original thread is here
there is a mention or ARCore, @TheGuz might have more infos on the tech needed.
also, the warehouse is growing these days, last weekend it was stuck, they had to catch up with the uploads, could also be they are working on it ?
