Approval Workflow: Encountered "Invalid" message when trying to approve a submission

Hi, we are having issues with an approval flow. One of the members is citing an error message when he tries to approve. It gives him a message saying "invalid." Any help is appreciated!

Hi saintemmelia, 

Thanks for reaching out to Jotform Support. Are you referring to the Approval Workflow on this form? As I checked, it seems you have multiple approvers on the workflow. Can you specify which email address encountered the "invalid" message when trying to approve a submission? Also, as the "Require Login for Approver" is currently enabled, can you confirm if that approver is currently logged in to their Jotform account with the same email address when they approve the submission?

After we hear back from you, we’ll have a better idea of what’s going on and how to help.

Thank you for your reply. The approver Tim is having trouble with the form. He has used it many times and approved many forms, but is only now seeing the error message. He is using the email address timothysricci@gmail.com

Hi saintemmelia, 

Thanks for getting back to us. I’m really sorry that this is happening. Is this only happening when trying to approve a single submission? If so, can you share with us the Submission ID so that we can check? We have a guide about Where to Find the Submission ID that you can check out.
