Hi @Aidin Azimi ,
Thanks for your post! You will be redirected to the default directory if you have one chosen as the default. If you are having trouble switching directories through the portal setting or due to browser caching, you can redirect manually to the correct directory by navigating to the tenant URL:
https://portal.azure.com/yourtenant.onmicrosoft.com
Otherwise your directory settings will route you to either the "last visited" directory" or whichever tenant you have selected as the Startup directory.
If you would like to leave any feedback to improve the experience you can do so in feedback.azure: https://feedback.azure.com/
