# Cookie Issues

{% hint style="info" %}
Please Note: Engage recommends using **Google Chrome** for the best experience.

If you received a message that your launch was unsuccessful, it may be because your browser is blocking 3rd party cookies. Cookies are required to sign in to VitalSource through Engage.

\
If you receive either of the below error messages you'll need to update your browser settings to allow Engage & VitalSource to set cookies.

If you are using an **Incognito Browser** on **Google Chrome**, please note you will need to add **both** Canvas and Engage and as *Site allowed to use third-party cookies.*

To do this go to Google Chrome -> Settings -> Privacy and Security -> Sites allowed to use third-party cookies. Click "Add" and enter your university specific Canvas URL, as well as your university specific Engage URL you see at the top of your screen. For example: *iu.instructure.com &* *indiana.courseload.com* or *uiowa.instructure.com &* *uiowa.courseload.com*
