This update makes messaging more reliable and fixes several issues reported by our users. • Messages sent while you're offline now go out automatically once you're back online. • If a message can't be sent, you can now retry it or delete it, so nothing stays stuck. • Opening a chat now clears "Mark as unread" as expected. • Tapping a message notification takes you straight to that conversation, even if you need to sign in first. • Leaving the app for a few hours no longer signs you out. • Searching inside a course now finds every lesson you can see on the screen. • Bold, italic and other text formatting in messages now always displays correctly. • When you add a link, the app now checks that it's a real web address. • The notification permission prompt now appears only once. • Signing out or deleting your account now stops notifications on this device. • Security and stability improvements.
