Good question! This is something important to understand about Tapas updates/notifications:
when you publish a new update/episode, all of your readers get a notification under the "bookmarks" tab/icon, and it gets assigned a new date/etc. and appears on the "Fresh" section of the website.
When you update an existing episode and click "send notification", it does notify your readers, but it does so under the "Bell" notifications, which only PC readers get to see. That tab just doesn't exist on the app lol. Similarly the date isn't updated, it doesn't go back up on fresh, etc.
Generally speaking you only want to use the update function to fix errors on pages (or potentially add new banners to the top/bottom/etc.). If you use the update feature to add new content, a lot of readers wont see it, sadly.
