Anyone ever have issues with the Mass Submit and Approve process for timecards?

Summary:

With the redwood upgrade, we are looking to start utilizing the Mass Submit and Approve process to approve timecards at the deadline. We plan to have timecards submitted by the manager prior to running this process. We haven't used this process before and are looking for feedback to see if others have had any issues with this process.

Content (please ensure you mask any confidential information):

Managers will move from using the submit and approve button to approve timecards to submitting only. Then at our timecard deadline, the process will run to approve timecards.

Has the process worked well for those that use it? Any history of issues with i?
