I decided to finally upgrade to a Jagex account, because of the extra bank slots it should give me. They have not shown up though.

I'm mobile only, so i'm just using the mobile app, not the launcher. logging in without problems after upgrading (I did have to sign out and login again once).

I'm also f2p at the moment, so that might be it?

Also, logging in on the osrs website, is there any way to check your account is in fact a Jagex account now, as opposed to a normal runescape account?

Hope someone can help!
