The initial advert plays normally, but once it's finished I'm greeted with the following message.
Sorry, the app can't continue playing your video because of an unexpected error.
Please check your connection.
There are no issues with my connection, episodes 1 and 3 play normally and I've rebooted my roku 1 box several times so the error is most certainly not at my end.
Crunchyroll app version 2.0.4
