How do I add multiple Instagram accounts with ECHO-ME?

ECHO-ME does not currently support adding multiple Instagram accounts directly. If you want to connect more than one Instagram account, you need to link them through Meta Business Suite first, where you add your Instagram accounts to your Facebook Business Page. To know this step, read: How to Connect Your Instagram Account to Your Facebook Page

Then use the Connect via Facebook option in ECHO-ME. Once connected this way, ECHO-ME syncs all the linked IG accounts and shows them under your monitoring accounts.
