Store session expired

So how is there not a fix to this yet? Kind of annoying how I go to the store literally hours before I visit again and all of a sudden I get the expired message and have to relog cuz it won't go away. This issue has been going on since 2012 last I checked from other forums. Can Riot really not just make a new session each time I visit the store or does it really have to remind me that my session from 5 hours ago expired and not let me visit again
