Upgrade Sling tv to latest version ... Finally figured out

I apologize if every person here knew how to do this.

Using firestick I tried to launch sling tv and got the message I needed to upgrade versions. There was not any additional info as to the upgrade process and clicking sling always gave the same message. I searched sling tv help site with no luck and called the tech help number. Gave up after hearing the same message over and over while on hold.

After wasting lots of time searching I did the following:

Firestick settings, installed applications, sling tv, uninstall.

I uninstalled sling, went to search for sling tv in apps and installed. Had to enter sign in info and now it works.
