Depending on which browser you're using, you'll need to adjust the settings for your browser.
Edge:
- In the upper left-hand corner of the browser bar there's a little lock icon.
- Click the lock icon and under "permissions for this site" we found that clipboard was blocked.
- Change "block" to "allow" for the clipboard
Chrome:
- In the upper left-hand corner of the browser bar there's a little lock icon.
- Click the lock icon, then click "Site Settings"
- Under Site Settings, look for one called "Clipboard" and change the settings to "Allow"
- The default is "ask" so it will always ask you and if you accidentally block your permissions, it will turn them off.
