Long Story Short:
Bought my Nan a Kindle Fire while it was on offer. I then ran a script to install Google Play, services and framework etc. Which worked and I could download from the Play Store as normal.
She likes it and can go on the apps, but won't understand downloading properly.
I went onto Google Play on my laptop on her account, attempted to download apps remotely, but the Kindle doesn't appear.
How do I make it appear?
