Fire Emblem Heroes keeps crashing: What to do if you receive Error Code 803-003

If you download Fire Emblem Heroes and receive the error message 803-003 while downloading content or using the app at any time, you have experienced the same error as plenty of other players. According to Twinfinite, Nintendo has yet to explain what the message entails, but it likely refers to a server problem and congestion with everyone attempting to download the game at once. 

Unfortunately, all you can do right now is continue to retry downloading Fire Emblem Heroes again and again until the error goes away. Instead of trying again from the same screen, however, back out completely to the title screen or close and reopen the app. Sometimes this will result in a connection going through. Otherwise, wait a little while (up to an hour) and try again. You may be able to get through if the server load has lessened.
