I'm installing SCA 2022.2 in Sandbox but cannot find the Base Theme bundle when I search by bundle Id provided in teh release notes, 454603, has it change?

Has it been provisioned to your account?

I did request it, but the strange thing is searching for the bundle on the Search bundle feature and adding the Id it doesn't appear for some reason.

Ive noticed this, too.....do we just install an older bundle then update it?

I don’t know what to say. 1. I have SC base theme 22.1 installed. 2. I click update bundle. 3. “This bundle has a follow on bundle that you haven’t been granted permission to.” 4. I get the provisioning team to provision it to my account. 5. I click the button again. 6. I click update bundle. 7. It updates and I get the new theme. Is this not the same thing for you guys?

No - this is for new builds that don't have the theme yet so there is nothing to update and there wasn't one in the repository. Sure enough, I just checked again and it automagically appeared!
