Thanks @KierstenAdmin. Glad we know what the issue is and that it is a matter of time and back-end processes to get people added. Now they also have a contact in RHLC to report issues regarding access.
I read on the web that on October 2020 RHCSA has got two new subjects: one is about the containers, and the other is about shell scripting. For containers Red Hat provided free course for people that bought the exam before October, but what about shell scripting course??
