Hello poltraf ,
Thank you posting this question.
It would usually take up to 48 hours for you to start receiving recommendations. As it is has been 3 days since you deployed the appliance and the problem seems to be with the credentials.
Please log out from the page and try logging in again using cloud services credentials for authentication instead of MYVMware credentials.You could also try logging on to the portal in an incognito browser window if the problem persists.
If you continue to experience issues , please share the account details using the following link so that we can investigate this further.
Submitted credentials via the link you provided me.
just back from a session with Kishore, and it was an easy issue to solve (well, not an issue at all): I have 2 organizations, and I chose the wrong one, on a vCenter were collector wasn't deployed.
Kishore found this navigating, from the upper corner right, under my account name, and then "Change Organization" choosing the right one.
