// This file, like AppBannerWrapperContext.tsx, is meant to be dynamic - update this as and when we need to use the NoticeBanner

// [Joshen] As of 19th September 24, this notice is around custom SMTP
// https://github.com/orgs/supabase/discussions/29370
// Timelines TLDR:
// - 20th September 2024: Email template customization no longer possible without setting up custom SMTP provider
// - 24th September 2024: Projects without custom SMTP will have their custom email templates returned back to default ones
// - 26th September 2024: If no custom SMTP, emails can only be sent to email addresses in your project's organization
// We can probably look to disable this banner perhaps a month from 26th Sept 2024 - so maybe end of October 2024
