Have both Fire and iOS versions, and all went swimmingly until Fall 2016, then what the heck, Pantone. I came to rely on your apps, which are not inexpensive as apps go by any means. Have put about $25 into them. I rarely spend anywhere near that on any app. Now, I type in a new color and stare at a blank page. Not cool.
