Issue with Pega mission exercise completion

I have completed half of the Pega Mission sessions under Pega final mission exercise. But I am not able to view the completion status currently and the completed exercise in App Studio also is not existing and I had to start doing from begining twice. PLease help me with this.

This is for Pega LBA 25’ version.

Hi Saranya,

I recommend reviewing the Pega Instance expiration policies. The link is available on every challenge and mission exercise page.

In summary, I see you initialized your first Pega Instance for the BA '25 mission exercise on 12 May 2026, and it expired on 20 May 2026, as per the Pega Instance expiration policies.

To prevent this, plan to complete your final mission exercises within the time. Always launch the environment directly from the Pega Academy lesson page rather than using bookmarked links, and try checking your progress in an Incognito window to clear cached session errors.
