OS: iOS 10.1.1
Model: iPad Air
When I start up the game, my login is successful; it then gives me a pop-up notification that the game has been updated, etc, and that I should update to the newest version for full connectivity. Clicking the Update Now button takes me to the App Store page for the game.... from where I have no option to install the newest version.
App Store's page for the game doesn't seem to register that I need to update; it just shows that I already have the game installed. The only option button for me there is "Open" the existing installed app, which just takes me back to the same screen within the game of telling me I need to update. I've tried accessing the App Store page on its own as well with the game not already running; it still does not recognize that I need to update to the newest version.
It did this at the last update as well; I must have tried dozens of times before it finally gave me the option to install the new version.
