When I deselect "Allow Logo Click to go back to Dashboard Menu", it still is returning to the list of dashboards. Prior to the flurry of hub updates over the past couple weeks, this restriction worked as advertised.
This is an issue, as I use locked-down web dashboards combined with this setting to restrict access to certain features for particular users. Now they have access to any dashboards I've put together, including those I've reserved for myself.
I don't understand your issue with the new dashboard. You can click on the top left icon to go back to all your dashboards.
You can also create a link tiles to another dashboard.
However, I will add this to my dashboard needs updating thread. This really makes no sense to have to type the link in a URL box. The dashboard link tile is a much better implementation. This seems like something that should be done behind the scenes. Just have dashboard link tile use the correct url based on what dashbaord link you are using. Why would I have to type a url to a dashboard with the system already knows it? This actually seems like a downgrade to functionality. The link tile should be for external links... The system should just know and use the correct link.
