How long it will take, do you have any idea?
@Victor Could this be affecting Conversion API too? I’ve connected a Dataset to WhatsApp via the CAPI section in ManyChat, I’m triggering Purchase Events but these events aren’t reflecting in the Dataset/Events Manager.
Please let me know if this could be the case, as this is a current request of a client and I’m unable to track events successfully in ManyChat.
Hi everyone! 
We’d like to share a quick update on the issue that was affecting the connection between Manychat and Facebook Ads Manager.
The good news is that, over the past few hours, the instability appears to be resolved for most accounts. We’re still monitoring things closely with Meta, but many users have already been able to and use the integration normally and link their flows to their Ads.
If you’re still experiencing issues, we recommend trying to access Facebook Ads Manager using your browser’s Incognito/Private Mode and attempting the process again.
Still not working? If possible, please record your screen (using a tool like Loom) showing the entire step-by-step, starting from the flow creation in Manychat all the way to the point where you attempt to link it to your campaign inside Facebook Ads Manager.
This will help us escalate your case to Meta’s technical team with as much detail as possible. 
Thanks again for your patience — and let us know in the comments if the issue is resolved for you, or if you’re still seeing it!
Have a great day!
