Errors

In case of error a popup message will appear indicating type of error.
Errors can vary but most common are:

"Summoner not found"
To fix this one - recheck and reenter summoner name. There can be diacritical symbol in it (french, romanian, etc characters that look like english letters).

"No champion mastery found"
Such Summoner exists but there were no games played and no champion score accumulated.
