Hello,

In learning ,My Learning - main menu , once entering the main menu there is no 'go back' sign/button, the only option to go back to the previous screen is by clicking on the home page . (when trying to click on the website back sign we get an error).

see screenshots attached ,
Please advise ,

Thanks,
Revital
