Steps to reproduce:
- Send yourself an SMS
- [As Expected] Note that (if locked) IntelliScreen/LockScreen shows that you have 1 unread SMS. IntelliScreen displays the contents and author of the SMS.
- [As Expected] Note that (if unlocked) SMS.app displays a badge with the number "1", signifying one unread SMS.
- [As Expected] Note that Tlert pops up displaying the text message you just received.
- Send yourself another text message, preferably with different content
- [!!!]Note that (if locked, and Tlert is set to ON for lock screen), IntelliScreen/LockScreen STILL shows that you have 1 unread SMS. The author/content are updated to the new text message, with the original text message being marked as read, despite potentially not having been seen
- [!!!] Note that (if unlocked) SMS.app STILL displays "1" in its badge, rather than the expected "2".
- [!!!] If you click the button to close Tlert, the number of unread SMS is now 0 (instead of 1), and the original text message pops up.
Unless I'm misunderstanding the reasoning behind this, it seems like an unintended effect that is quite serious, and could very well result in SMS messages going unnoticed if another is sent afterwards without the first being read.
EDIT: Also, if you disable Tlert in the lock screen, get an SMS message, then view it with IntelliScreen's QuickView (and thus marking it red), Tlert will still pop up with the message after you unlock.
