Premium not working

Was excited to use this app as I have thousands of contacts - but even though I upgraded to premium the app still prompts me to upgrade. Ive closed my browser, signed out and restarted my computer after agreeing to the subscription, and even tried to use the phone app - no luck :( Plus when I try to add my google contacts as a phonebook, FullContact says that phonebook is already synced (yet the app isnt noting it anywhere).
