No longer receiving email reminders to submit timesheets

Hello,

Some users in my organization have reported that they are no longer receiving email reminders to submit their timesheets. Their accounts are linked to a timesheet profile that is configured to send these reminders one day after the timesheet end date. I use the same timesheet profile and receive the reminders as expected.

Is there a specific setting (maybe at group level) that might have disabled these notifications for them? To my knowledge, there is no setting as such. I reported this issue to Workfront support a month ago, but they have not identified the root cause.
