I tried using the #google-drive integration, but later realized it cannot handle folders. I only need it for linking project folders, not individual documents, so it is useless to me. I was able to remove access from the Google account, but the field is still showing up in Asana tasks, despite the integration being now disconnected and hence, becoming a useless field.
I was not able to find any information on how to disconnect the integration, and if I click on “integrations” within Asana, it takes me to a paywall about upgrading to the Enterprise plan.
