I have refreshed my permission a dozen times but my manychat account seems broken

I recently made some changes in my meta business portfolio, but I did not expect that was going to damage the connection with manychat.

I have tried to re-connect it multiple times, trough its facebook page, trough instagram, but nothing works.

Manychat says the connection has been done, but I don’t receive any messages in inbox, and none of the automations I have work.

Please if somebody can help me, I’d appreciate it.
