Cannot Download Instagram/Redownload Unavailable with this Apple ID
I have two Instagram accounts, one personal, one professional. I.e., two separate/different Instagram IDs and two different passwords for each Instagram account.
I have two cell phones, one for work (iPhone 6+) and one for personal (iPhone 5s). If it matters, the phones have two separate wireless company accounts, as well.
Each phone has its own iCloud/iTunes ID.
I purchased the iPhone 5s last May 2014, and the iPhone 6+ in December 2014. Thus, all of my personal accounts were set up on the iPhone 5s, first.
I have the two phones set up on Apple's "family sharing" via iTunes, in order to access and share some of my data, calendars, etc.
I have Instagram set up on the iPhone 5s. I can login in to either of my two Instagram accounts on the 5s, but I do have to login/logout of the app and reenter each ID and password for each Instagram account.
I want to install Instagram on the iPhone 6+ that I use for "work" with my professional Instagram account. When I try to download the app to the iPhone 6+, I get the message that "Redownload Unavailable with this Apple ID." Please see the attached image.
I have tried different methods, but I cannot download Instagram to the iPhone 6+. Instagram says to go to Apple Support (https://help.instagram.com/126971294119253/) and Apple Support, as far as I can tell, considers this a 3rd party app and it isn't their problem).
I have looked at some solutions -- such as logging out of iCloud and iTunes on each phone, and then logging back in and downloading the Instagram app, but it appears that I will lose the data I have on the iCloud for each phone, if I login/logout of iCloud and iTunes on each phone.

This is completely stupid -- surely individuals within families have their own Instagram accounts and post from their own phones. And this is a free app!
Any suggestions as to how to download Instagram to my iPhone 6+ that don't involve losing any data?
Thank you!
