If Pretendo don't address error 104-2210 on this game i might lose my mind. It is very annoying to constantly delete share data in the settings. Pretendo please address and fix this and my life is yours.

you must not complain, in my case, error code reappears althought i deleted share data
Inkay 2.6.0 fixed this issue. Make sure that you are not starting Splatoon from the Quick Start Menu, as that causes issues with BOSS data
