What other issues, I might be able to answer some here

If you are using an instant watch event saying, trigger when the issue is approved, you can pull the userID from the event time bundle at the bottom. If not I suggest looking into the API to find something https://developer.adobe.com/workfront/api-explorer/  

Update: I used the API module to subscribe user(s) to an object. If anyone has a better way please enlighten me. Also I forgot to change the obj code from proj but it would be whatever obj you're subscribing to. 

Using Fusion how do I subscribe a user to a given project? I looked at the API but I can't seem to find a module add a subscriber and I don't know what API call I would use to add one.

You cannot change who the email comes from. The email comes from the account associated with the connection to WF. I would create a bot account connection or have an automated message on the update. Our bot connection is called System Process and Adobe support can help you set it up. Email notificat...

This is what you should see, I didn't have it directly because the servers were down for me yesterday. Fill it out like I have listed above. Select Program for the field. Put the Program ID in object ID. The message in update text. Lastly the specific users/team to @ in notify.

I didn't know if this was a global thing or a just our company thing. When I checked the system status it said there was no problem with WF. I have emails on for all Fusion related things and I know that they don't actively monitor the forums I was just wondering if it was happening to anyone else.

I keep getting this error when working in Fusion with any WF connectors. Some of my connections are working like Microsoft 365 email and others not working like any WF connectors and Microsoft Excel. Is anyone else having issues right now? 

Have you tried Create Record -> Update, Select all fields except last if not applicable:OBJ code "PRGM"Program IDNote MessageNotify user(s) or team(s) if applicable

One thing that I forgot to mention was that Fusion put the "+" symbol there because it was trying to concatenate the strings together. Glad I was able to help!
