Transmitter issues yay

Installed a new transmitter less than a week ago, and today the app has decided not to recognize it. I snapped the picture of the box, and it started to act like it was going to recognize it/sync and then changed its mind and stopped recognizing it again. Going to use the actual Dexcom reader thingy to try and troubleshoot but I am really not happy right now.
