See only what your plan offers.

In the onboarding wizard's plan window, the discount options shown used to include Fixed amount and Flat rate pricing even when your Subi plan didn't include them, with the restriction only enforced (inconsistently) after the fact.
The wizard's plan window now shows only the discount sections and choices your Subi plan actually includes; a dismissible note lets you know more options are available on an upgrade.
Behind the scenes, saving a plan with a discount type your Subi plan doesn't include is now blocked outright, across regular selling plans, mystery box, membership, and AI-drafted plans, rather than being accepted in some paths and rejected in others. A gated discount type can no longer reach your Shopify store for a plan you're not entitled to.
This change applies to the wizard's plan window specifically. The plan window opened from your Plans page is unaffected, and an item already set to a locked type before this change (for example after a plan downgrade) still displays as before.
