Upgrade prompt
The upgrade prompt is what you see when a free-tier action — adding a second asset, or inviting a fourth member — would take a syndicate over one of its limits. The action is always blocked; what differs is how the user is invited to upgrade.
- On web, a dialog offers Cancel and Upgrade Now. Upgrade Now opens the checkout URL in a new browser tab — there is no email.
- On iOS and Android, a snackbar shows the limit message with no call-to-action button (App Store and Google Play rules forbid it), and the app automatically sends an upgrade email to the account holder’s email address. No user interaction is needed to trigger the email.
The web checkout path depends on a payment provider being live — currently dormant. See web-email-handoff.
