We’re waiting on both Pinterest and Instagram to give us direct API access.
Unfortunately there’s no estimated time and there’s not that much we can do about it.
Apologies for the inconvenience and hope to have your undestanding.
P.S. You can create multiple free Zapier accounts to bypass their free plan limitations for Instagram. We’re seeking another alternative for Pinterest as Zapier now considers it a Premium app.
P.S 2 Even if you use Zapier directly, they don’t provide a UI where you can create posts for Instagram or Pinterest.
