Hi Alecia,
Workfront provided the explanation below under case number 00399278 I submitted this month. Unfortunately it appears the ease and ability to commit to new dates and have those dates accepted by a project owner was removed when new commenting functionality was rolled out and now is being positioned as an improvement that needs to be built out, however it has been available for years. Argh, frustrating.
After investigation, Our development team does recognize that there is indeed an issue here that they need to review in more detail. However, because of the time and effort it will take to build out the improvement, the work for this fix has been converted into a story, which is not something we can keep a support case open for. Stories are work items that are added to the team’s backlog and worked on over a period of time. There are no ETAs given on story work due to this.
