In 21.0, when hitting the Home button icon, it will take you to the last dashboard viewed in the browser tab rather than the home dashboard. In 12.3, it would take you to the home dashboard always.
The link on the lower left hand side in the browser for the home button will show https://[automic_url]:8443/awi/[client]@home and if you go to that URL directly, it will take you to the home dashboard.
If you open a new tab and hit the home button, it will go to the home dashboard.
If you log into a new session in a different browser, it will go to the home dashboard
If you open a new window in the same browser, it will go to the home dashboard
It's only in the same tab without reloading that will go the last chosen visited dashboard.
There are other things that work like this as well - when going to Administration, it will first open to User Management -> Users. If you go to Administration -> Automation Engine Management, then to Process Assembly, then back to Administration, it will still go to Automation Engine Management whereas in 12.3 it would always go to User Management -> Users.
This is caused by the new 21.0 design of the AWI
This behavior is considered as designed. The design was changed with the updates to the AWI for 21.0. Some information on this can be found below:
This is a slightly different navigation concept that was introduced with the version 21.0
With 21.0, there is too much that would need to be re-designed with the code that could lead to other problems to change this at this point. With that being the case, a feature request/idea would need to be created here: https://community.broadcom.com/ideation/allideas?Page=1&CategoryKeys=1e4ef0d7-da0d-4d8b-9139-87c7105799c8&StatusKeys=&Sort=MostRecent in order for this to be considered for a future release.
