Zoom Phone for Salesforce content is blocked error (CSP directives)

We recently started testing Zoom Phone for Salesforce and have been relatively pleased. It seems to be working well in our sandbox environment, but when we transferred it to production, our users are receiving the following error when they try to access the soft phone: "This content is blocked. Contact the site owner to fix the problem." They are not able to log into Zoom or authorize the installed app.

Upon doing some further digging, it seems this is related to Salesforce's  updated CSP directives. Our production environment is testing this new release update. When I disable the test, Zoom Phone seems to function fine. However, this change will be enforced in the next Salesforce release, so I'm concerned that Zoom Phone will no longer function. Any suggestions would be appreciated.
