Read AI uses recording notification to let people know that the meeting is being measured, as Read needs to access audio and video to generate the meeting reports. After the call, Read generates the meeting report based on the plan level of the user(s) who invited Read to the meeting. Enterprise and Enterprise+ are currently the only plans that support audio and video playback.
If you are not on the Enterprise or Enterprise+ plan, you have 30 days to upgrade to one of those plans to unlock audio and video playback for your reports. When you upgrade to a new plan, as a courtesy Read will automatically go back and reprocess all of your meeting reports from the past 30 days to apply the features of your new plan. This includes unlocking reports that were out of quota when upgrading from Free, and enabling audio and video playback when upgrading to Enterprise.
Note that Read users only any plan can configure their settings to disable audio/video playback in meeting reports, even if their plan supports it. This setting is located under Account Settings > Report Content. Like most account settings, this may also be controlled by your Workspace, if you belong to one.
