I see: "Someone else is already recording on this account" or "A recording is already in progress"

Can't begin recording in the studio because of the error message: "A recording is already in progress", "Someone else is already recording on this account", or "Start recording failed"

Suggested troubleshooting steps

Using a computer, as the host or producer, reset the studio page that shows the error:
1. In the browser's address bar, Reload/Refresh the studio page.
2. At the bottom of the studio page, click Leave, then End session for all.
3. Click Record again to test.
  You and any other participants will need to rejoin the studio.
If you have no incomplete track uploads, clear your browser cache, quit and reopen your browser, and log in to Riverside again.
Check to see if any other studio you recently used is still recording:
1. On the studios list, look for the · REC label next to the studio's name:
2. Enter the studio, click Leave, then click End session for all.
3. Click Record to see if the error occurs in this other studio, then Stop the recording.
4. Repeat steps 1-3 for any other recent studios or studios with the · REC label.
5. Return to the original studio with the error and click Record.
