Administrators for users at their company need to be able to use the Marketing Cloud Admin Console to assign the Landing Page for users. We should not need to instruct our users (and users should not need to remember) to click the totally non-intuitive '9 dots' icon in the upper right menu, then click on a product icon to access it.
If Adobe is requiring customers to migrate all of our users from each product level authentication (e.g. our legacy Adobe Analytics IdP SSO login method) to Adobe Marketing Cloud authentication, customer admins should have the ability to make that transition to Marketing Cloud authentication (e.g. Federated ID SSO login) as seamless as possible for their end users.
Adoption and use of Adobe Marketing Cloud applications by users within my company is paramount, so avoiding and minimizing any barrier is critical. They are often looking for a reason to say "it was too hard to use" or "I couldn't figure it out" when we are asking for them to take it upon themselves to leverage these tools, rather than expecting "the trained expert" do it for them.
This is the one barrier preventing my users from using a bookmarked link to authenticate and be taken straight in to Adobe Analytics, where I can already set their initial view.
