Application messages in status of Waiting

Hi @LucyWang,

1. If you RMB on one of the application messages and select “Show Details...”, do you see any error text? 
2. You could try doing an RMB →  Suspend and then RMB → Resume to see if the application message starts processing. 
3. You could also try RMB → Move to Queue and move it to a different queue that you know is working and then do the same as in step 2 above, if it doesn’t start processing in it’s own.
4. You can also check the Message Queue settings for Notifications queue from Setup IFS Connect window. Make sure the STOP_QUEUE check box is unchecked. Also check the EXECUTION_MODE. If it is set to InParallel, try setting it to InSequence and try the above steps 2 and 3.

Hope this helps!
