My friend, I have exactly the same problem. I've been having this since Monday too. And the support team is very complicated to respond to me every 24 hours.
I was worried because I didn't see anyone reporting it, I thought it would only be on my account. But now they started reporting it.
If you manage to solve it, please respond here.

I've done everything, I removed all permissions, put them back, validated everything and everything is correct.

Here the problem happens when the contact comes from Instagram ads. What about you too?

Same here. I have an automation to trigger when an Instagram post gets a comment. And nothing happens.

I’ve been having the same issues since Monday. No new contacts are being added from Instagram.

Hello, everyone. Any news for you?
Everything is at a standstill here!

Try removing your page and then add it once again, make sure it’ll delete all the contacts, so backup them if it’s imp for you! @robozinho777 @bruno.ferreira @Andrew X Chrissy @pinnacleconcealment
