WHY, exactly? The Nvidia Shield tablet is one of the best tablets available, and its specs are pretty close to top-of-the-line.
It is really infuriating that so many of Adobe's mobile apps aren't even available for Android — and many of those that are available on Android won't work on my Shield tablet.
Frankly, it seems like Adobe doesn't really care about customers unless they use godforsaken Apple products.
You are right about Capture; it's not yet available for Android tablets. But, I believe the Nvidia Shield is one of the tablets that is supported for Adobe Draw for Android (and, also, the beta versions of Comp CC for Android and Adobe Sketch for Android... which are available on by joining Adobe Android Apps - Community - Google+).
Have you been able to get Draw for Android on your tablet? If not, what version of the OS are you using and what version of Draw for Android are you using?
Let me know.
