Starting last night around 10pm EST, the TDN service has been unavailable. Tested with both iphone and android. Still not working this morning 10am EST. App deleted and reinstalled on both types of phone multiple times. Once you log into the app, if you try to flash or datalog the app kicks you back to the log in screen and its over and over and over. Also linked tuners have disappeared.
Someone from HPT please get on this and get it figured out.
