maybe i am missing something but i can't seem to get into service desk on my tablet.

i used to be able to surf to www.gotoassist.com on my tablet and then login so that I can access service desk tickets when I am on the road.   now, I cannot find the login spot on the website.  I have checked all the gotoassist apps in the playstore but can't find anything that is giving me access to service desk.  I do find all the remote assistance apps but nothing on the service desk.  what am I missing.   (both android and windows tablets have the same issue)
