Hey, I'm sorry about that. Have you tried clearing the cache on your system, hard resetting it (power cycling the system), and as well as uninstalling and reinstalling the game?
If your daily tier skip is still not counting after trying those steps the best suggesiton would be to report it over to official support. They will be able to gather more information and assist further as soon as possible:
