Actually it still doesn’t work with the Basic plan. Only certain API calls. The ones I need like HashtagMedia fail regardless of which account I use.

If I logout and use a different account with your Basic, unpaid plan, it works. But when I am logged in using the plan I pay $100/month for it doesn’t work and I get an error
