What happens to my automations, CRM connections, Zapier and API keys if I downgrade?

They pause on plans that don't include them and start working again when you upgrade to Pro or Agency. Settings shows them under "Still connected from your old plan", and you can remove any you don't want; a removed one is gone for good. They're saved for 90 days. After 90 days on a plan that doesn't include them, they're removed, and you'd set them up again once you're back on Pro or Agency.
