Fixing Microsoft Edge Microphone Permissions on Desktop
If you didn't receive a pop-up, then you might see a microphone icon in the URL address bar. Click on the Microphone, and then change the option to "Always allow https://app.caption-ed.com to access your microphone", and then press Done.
Otherwise, within Microsoft Edge, click on the three-dot icon in the top right-hand corner of the page and choose "Settings".
In the sidebar down the left-hand side, choose "Cookies and site permissions" and click on Microphone.
You will then see the website address for Caption.Ed is on the list of blocked access. Simply click on the trash icon to remove this, and then you can close this setting page and refresh the Caption.Ed website, and you'll see the pop-up window appear.
