Hello, I am writing here because from my BUSINESS MANAGER account I can no longer find the icon to access WHATSAPP MANAGER that I had previously configured. (image attached)

I can no longer find this function. Some time ago there was a large icon at the top "QUICK LINKS" now it is no longer there and not even in the other links below

Where can I find it? I should configure some functions and schedule other messages.

Thank you very much everyone. Mauro
