This is the method of choice in order to disconnect Crmble from your Google account. This has to be made on every Trello board with Crmble in which a Google account has been connected.In Settings/Toppings/Google you can easily disconnect your Google account from Crmble clicking on the trashcan icon. By doing so, Crmble will automatically disconnect every Google Service including any Google Form connection that has been established with Crmble. Signing in again will not reestablish previous Google Form connections, but will re-activate Google Sync functionality and GMail tracking (if toggle is on).
