# G2M wont start with MHub

02.09.2026

We are currently seeing a problem in Chrome and Edge browser where G2M will not start in the same window as MHub.

In Firefox browser, this is normal behaviour due to technical circumstances in Firefox.

We are working on the issue, until a fix is found , this workaround is possible:

You can run the G2M in a separate tab or window:

Select "Start WebApp"

You will now have 2 tabs, and can swap back and forth between them.
