Hi Nuria, I can't speak to the source of the glitches, as Workfront is a large, complex application with many different teams working on many different areas. I would ask you to submit a support request if you can provide a specific scenario that isn't working as expected, and we can assess whether or not the issue is related to an open defect, or whether it's a new defect that needs to be reviewed. Thanks! Dustin Martin Assigned Support Engineer Workfront
