All PSB standard license customers have been migrated to use the profile editor in new PSB portal
we have just completed the profile migrations for all PSB standard license customers on EMEA (PSB1), AMER (PSB2) and APAC (PSB3). So starting from today, you should be able to do all your tasks in the new portal, except one: adding more subscriptions to your company is not yet available in new portal. That will be added in next release within 2 weeks time. So until that time you need to add new subscriptions to your company from the old portal.
PS. After just few weeks of the release, we already have ~20% of customers migrated to use the profile editor in new portal.
