Hello,
We have setup a weekly e-mail reminder for timesheet registration, but not all of the users get it. I checked the batch job associated with it and the infolog shows the message below:

As far as I know, the e-mail ID is the one from Users, which they all have filled. I noticed however that on the Worker form, not all of them have set Primary checkmark on their e-mail address. Could this be the reason?
Is there a way to check to which form the Infolog referrs?
Many thanks!
