Users receive email invitation but can't access to quiz

[julioo]

Hello,

I've installed the Quiz app in apex.oracle.com instance.
Made my poll, invited by email users. Email are received but once open the link we get the follozing error

Session state protection violation: This may be caused by manual alteration of a URL containing a checksum or by using a link with an incorrect or missing checksum. If you are unsure what caused this error, please contact the application administrator for assistance.
Contact your application administrator.

Any help ?

This bug was actually fixed on the same day you left this comment and the fixed version of the Poll starter app is available now.
