To see Instagram content on your UPshow screens, you must use an Instagram For Business account and your Instagram account must be connected to a Facebook Business Page. This a requirement from Instagram (which Facebook owns).
If you are still running into problems connecting your accounts, here's the basic troubleshooting steps to follow:
- Make sure you have an Instagram Business Account
- Connect your Instagram Business Account to a Facebook Page
- Make sure you are the Owner of the Facebook Page you connected to (This especially important if you didn't create your company's Facebook Page)
- Once everything's set, add your Instagram Business Account to UPshow
