Sage CRM 2022 R1 download

How can I obtain the 2022 R1 download?  When I login to the portal, the only download that I can see for 2022 is R2.  Unfortunately, I have not been able to upgrade to this without errors. 

Information in the following post indicates that upgrading to R1 first and then R2 resolves the issue.

Therefore, I wanted to attempt this upgrade in my sandbox environment.

Any assistance would be greatly appreicated!
