Here's how you access the controls to turn Calendar Signatures Off or On:
Zoom App
Opening the Warmly App through Zoom
Clicking the You tab
Clicking and scrolling to the Calendar Signatures Section
Toggling "Enable Calendar Signatures" and "Enable Calendar Signatures for recurring meetings"

Web Browser
You can also achieve this by
1) Logging into your account via warmly.ai using a web browser
2) On the left hand side, click the You tab.
3) Toggle to the Calendar Signatures Tab

FYI
As a heads up, if you’ve enabled our Calendar signatures feature, we don’t delete them off previous and recurring events. We simply don’t add anymore. I hope this helps!
