I am experiencing the same difficulties. Having attempted all suggestions listed in this stream of postings. Now I do not even get a flashing red light.
My adobe ink has NEVER worked as a normal stylus in any other applications. After I purchased it, I thought that I must have misunderstood its use--I certainly would not have purchased a stylus for use on only 2 applications--but oh well. I have NOT recommended adobe ink to anybody. I have told everyone to stay clear until issues like this are resolved by the developers.
I suspect most users are experiencing the same problem but are just too disgusted to try to figure it out.
what a massive disappointment this purchase has been so far.
