Can’t download Photoshop CC to iPad - IOS up to date, other mobile apps installed & working.

[#1]

Hello Community! I am stumped!
When I go to the App Store to download the mobile version of PS CC, the button to click is ‘grayed out’ - yet other mobile apps like Behance, Draw, etc. are all available for me to download and use fantastically. 
Latest IOS on IPad, lots of storage room, up to date billing to CC etc. 
Can anyone think why? I do have the Adobe CC app on my iPad, and when I click to open Mobile PS CC there it takes me (as it should for downloading) to the App Store (which is also up to date, etc. with acct info.) And that’s when, it feels like the Microsoft ‘black screen of death of yor’- the button to download the app to my iPad is grayed out and not allowing me to click on it. 
Help... Thank you so very much!

What is your actual iOS release (numbers, not “latest” please), and exact iPad model?
