Troubleshooting Studio on two tabs

Last updated: August 1, 2025

When Zuddl Studio is open on more than one tab, an error message shows users that Zuddl Studio is already open.

To fix these errors, try these troubleshooting steps:

  • Check the web address for typos

  • Make sure your internet connection is working normally

  • Check device settings

The error message is not shown in some edge cases:

  • Some users join on two tabs and still are not shown the warning message either because tabs have been idle for a long time or because certain ad blockers interrupt the connection

  • In some firewall conditions, multi-tabs aren’t detected, and thus, the error message is not shown

  • Based on the user’s device settings, if a studio was previously opened on one device and later was closed, and the same studio was opened on a different device the message may not be shown.
