I'm still logged in on both the game and jagex site on my mobile, but I'm trying to play on my pc and it's not sending me a code. I tried 2 hours ago and I've tried a few times in the past 30 minutes.
I was playing on my pc fine 12 hours ago.
I've tested sending emails to my email and i'm receiving them fine. It's just not receiving anything from Jagex.
edit--
just made a support ticket and it sent the email about it fine. so I don't understand why it's not sending login codes
