I use Windows 10 and Windows Edge browser

I play on the Dark Plains server

Screen keeps showing me an arrow that I can upgrade troops in the Hall of Shadows but when I go there and scroll through my troops after I select the Upgrade tab on top, there is no option to upgrade any of the troops in the Hall of Shadows.

I just realized the problem, disregard the post, need to upgrade the Call of the Blood to lvl 3
