Project Online 'Submit' button is greyed out and the workflow is stuck at processing stage.
I created Project Online workflow using SharePoint Designer 2013 and published it. The workflow contains no errors as validated on SP Designer 2013. I create a project using the EPT that is linked to the published workflow, and updated all the mandatory fields. However the workflow submit button is greyed out even after I saved, published and checked in the project. the workflow is stuck at processing stage and it still the same even after I restarted it few times. Please advise how to make Submit button to active.
