Auto-publish doesn't work for Instagram (Adobe Express)

[Dirk25215832lufr]

I would like to auto-publish my content on Instagram and Facebook through Adobe Express, but for some reason, Adobe Express thinks I'm logged in on my personal account. In fact, I am logged in at my business account on Instagram and I already switched a couple of times from business to personal to business, to see if that helps.

This is what Adobe Express says:
You need our mobile app to publish this post on Instagram
Reason: Instant publishing is not available for personal Instagram profiles
We'll send a notification to your mobile device for you to manually publish this post. 

Anyone who knows how to fix this problem?

When you are logged in to Express on your business Adobe ID, and you go to Schedule > Setup, is the Instagram account under connections a business Instagram account? Have you tried disconnecting and reconnecting the Instagram account under connections? Just want to clarify the difference between the Adobe ID account you are using to log in to Express and the connected social accounts within that ID, in case anyone else here can offer further help.
