Why aren't my stats updated?

There may be occasions where the update of the entire page may be interrupted due to the overload of Riot Games or OP.GG servers. 
If you can't see the latest matches even if you click the Update button on your summoner page, it may have been caused by the following reasons. 
1. Temporary delay  or data missing on the League of Legends official API server
2. Temporary delay due to overload on OP.GG server 
It's a temporary server issue in most cases, but please open a ticket if the problem persists, including the summoner's name, server, and details of the missing match.
