Until Patreon takes it away:
> As a result of Apple’s mandates and in order to make sure that you can continue getting new members in the iOS app, we've started a 16-month-long migration process to bring all creators onto subscription billing by November 2025, supported by a roadmap of new features and tools to make sure the billing model works for you, your community, and your business. To be clear, this means that first-of-the-month and per-creation billing models will be discontinued in November 2025.
