So first go to your steam page like this and press at steam on top left corner 'check spoiler'
Then you go settings 'check spoiler'
Then you press on Account if it's not on it and you will see like this 'check spoiler'
Press at CHANGE... and you will see like this 'check spoiler'
Then you need to press at 'Steam Beta Update
' like in this picture 'check spoiler'
Then restart your steam, once your steam restarted repeat the steps above and then change it back to NONE like in this picture 'check spoiler'
This should solve your problem in jailbreak.
