I want to send an email campaign inside of Zoho Mail. When I click on "campaigns" an important update pops up. There isn't an 'X' to close the pop up and I am unable to scroll down on the pop up. The scroll bar scrolls the actual page behind the pop up. I can't access Zoho email campaigns because of this pop up. I'm stuck and unable to move forward. How do I close this pop up to continue my work?
