@Sophie for some reason, the app was working fine for a few weeks then all of a sudden the Xbox store was having issues and at the same time, I wasn't able to launch the Funimation app. Could be coincidence, I just assumed that was the issue.
However, it seems the issue is still persisting. I launch the app, it remains on the blue screen with the white smiley for about 3 minutes and then says "network error, check your internet connection"
My internet connection is perfectly fine. I've been gaming and streaming other apps just fine. It just won't let me start the Funimation app. I've tried uninstalling and reinstalling the app but no success.
