Hi, @MyclassRemote,
Welcome to the Developer Forum! There are a couple of scenarios that could trigger the “Unable to install this app because it needs pre-approval by your account admin. Please contact your account admin for more details” error message. Please see our developer support documentation and let us know if you have any questions:
No, changing the settings will not affect the online lessons (Zoom meetings) or the instructors who have already approved the app. The admin of the account for that user may have to install the app so the user can install it. I’ve linked our documentation on the Pre-approval request flow for Users for reference below:
