Thanks. Damn, must just mean it's not available for my phone then. Thanks Adobe!
It's not compatabile with any of my devices. LG G3, Samsung Tab S, Samsung Tab S5E, or Honor View 10.I had a quick look using my old P20Pro and found if you use Google to search for the app and then link to the Play Store it shows up, but with a not compatible message.
Though it works on the OnePlus 7 Pro, so maybe it's the Kirin chipset that is to blame.
