Currently i'm not able to hide projects in new Jira Cloud experience, in the previous version i configured as Closed Project using a different scheme, but this scheme isn't longer working in new Jira Cloud. Can you please help me?
It's pretty late to respond, but I try to provide helpful information to someone who encounters the similar issue to you.
Apart from the unexpected behavior you've described, please also consider to watch and vote JRACLOUD-1450 which makes you able to archive projects.
