email option not available on every flow for tiktok

when i first using the tiktok automation I notice you do not have the option to add a link to the button. Then I fought out you have to add the link in the email. So I create the flow. When i went back to create the next tiktok flow/sequence the option was not available. and on top of that manychat wanted me to pay additional $29 to use the AI when I`m on a PRO plan and I wasn`t using a AI feature. Now I`m just setting up a regular flow.
