Can't use genius

For some reason, my <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> app won't allow me to use the genius tab. It completely freezes. I have reset the app, uninstalled then reinstalled, and reset phone. Has any one else had this issue? How did you solve it? I emailed app support three days ago, but haven't gotten a reply.
