Just updated the battle.net app. Closed and restarted it and now I’m just getting a blank clear or Black screen. If I uninstall it and reinstall it, it works fine, but it asks me to update and close the app. If I do that again it’s giving me a clear / black screen again.
Something with the update is messing it up. I am using the beta version of the app. Not sure if that is what is causing the issue.
EDIT: Looks like my video driver updated and that also caused the issue. Downgraded to an older driver and now it works correctly.
