Why does it happen and is there a way to solve it?

I have 2 accounts.

Account 1 - 500K followers, monetization is not available (except LIVE) since the account country of origin was a third world country.

Account 2 - opened in US and now it is saying account not recommended. Only have 1.3K followers. I only posted family life and stuff. Total 11 posts. Account check came back clear.
I tried to send messages to Support and only got AI generated responses.

Q1 - Any idea on how to solve it for account 2?
Q2 - Is there any way I can monetize the account 1, like an actual account?
