Due to the recent hurricane in the US we are experiencing issues contacting Instagram and Apple to expedite the issue.
Please be patient. A new version will be available soon from the App Store. Instagram support is looking into the OAuth issue as well.
Thank you.
InstaTags App Team
Update:
InstaTags - Hashtag Manager (v1.0.2) is out on the App Store!!!
