Does anyone know why I get the error "There is no valid plan with this identifier connected to this app."?
I connected my site to memberstack > added the data-ms-modal="signup" custom attribute to the signup button in webflow > i test it on staging and the signup modal appears as expected > then when i try to sign up I get the error above.
I haven't created any plans, I want members to sign up without a plan, then select one later. I have set default redirects.
Really appreciate any help!
