Your CRM Setup setting can be found under your Admin Tab:
Using the Podio/Salesforce Setup setting, you have the option to:
For Podio Users: either change your contact app or reinstall your communication app. Only the main administrator (the owner of the account) has access to these settings.
For Salesforce Users: to create leads for unknown callers or/and autocomplete new tasks if you toggle these options on. The Account Owner or the Admin can change these settings.
