Free Oracle cloud account for ODSA

Summary:

Hello,

I'm trying to use the new service recently announced ODSA, using the documentation I've found here https://docs.oracle.com/en-us/iaas/Content/multicloud/intro.htm. I manged to link my Azure subscription with the Oracle one, but after that I get errors for every click I do (even for the integrated support page). If I want to create an Autonomous DB, along with the errors received, I can't even choose the Database Version because the select list is not opening. I also use the recommended browser (Google Chrome, last version). Any idea or suggestion what to check more? Is this working with the free trial from Oracle Cloud or is available only for paid subscriptions? Thank you in advance!
