If you are using the Windows copy of Desktop Edition, try this @Mohamed_Hamza:
- Open the regular Manager application (not the web browser)
- Select the business you wish to access
- Right-click the tab you want to open - e.g. Sales Invoice - and choose ‘Open in New Window’. You may also be able to do this by Ctrl + left-clicking the tab.
The application should automatically send you to the correct port.
If I understand you correctly, you don’t actually care about which port the application uses. What you care about is that you couldn’t bookmark the login page in your web browser?
Note that the third step above does not work in macOS, due to a difference in how the web view is rendered within Manager on that OS.
