Whenever i have issues logging in, I just go to citithankyoucard.com I have the webpage put into favorites on my phone and I just replace the saved webpage. For whatever reason the webpage stops allowing me to log in every so often and I just need to "reset" it by going to citithankyoucard.com and let it generate an updated login page or however it works.
