We want to switch our subscription to subscription group but we can't find any way to test
- Upgrade.
- Downgrade.
- Crossgrade.
When we try to purchase a product from the same group we get a message (from sandbox) "You're currently subscribed to this." with [OK] and [Manage] options.
However the [Manage] option is not working on the sandbox.
How can we test this? Is it only testable on live environment and not sandbox?
Thanks
