On older app versions on Android, we are aware that the Favorites and Recent tabs are not working properly.
The issue has been fixed in the latest version 3.9.6. To update the app, go to the More tab, choose Check for Updates.
After updating the app, please go to the Favorites tab and pull the page to refresh. It should show you the missing favorite updates. Otherwise, please kindly wait for the next waves of new chapters to come in. The tab should show new updates then.
We are incredibly sorry for this inconvenience. If the issue still persists, please contact our Support Team. We will get back to you ASAP.
