On web or mobile? The web one has always just been a process count, and on iOS we just changed it to match that. It did have a process list before, but it was buggy and expensive CPU/battery/data wise to keep up to date. We figured it wasn't a core part of what Cayenne does, so reduced it to a count.
If you do still want to view or manage your Pis processes through Cayenne, you can use the Remote Access feature to connect via VNC to your Pi and run
top or any other processes manager of your choosing, graphical or command line.
