Hello @Innova thank you very much for bringing this up here in the community 
I just wanted to step in with a quick update. This issue is currently being investigated by our dev team. So far, it has not been confirmed whether this is an issue on our end or not.
It is possible that this is caused by Facebook access permissions. Currently, it seems that the pages don’t load when also connected to an organization inside of Facebook Business Suite for ads. When the page is removed from the ad account, it seems to start showing up.
I will make sure to monitor this issue and will post an update here as soon as I learn anything new. If you’d prefer to receive updates directly in your inbox, you can open a ticket with us and our support team will automatically notify you once there’s any news to share regarding this matter.
I genuinely apologize for any frustration or inconvenience this situation may have caused you. Thank you very much for your understanding and for bearing with us
A quick note: We removed your last comment from your previous reply as it was against the Community Guidelines which prohibit recommending or promoting competitor solutions here. This is to ensure the community’s integrity remains intact. Thanks for understanding.
