According to the manual, the Cory Wong plugin doesn’t mention the metronome so doubtful it is included currently. All plugins are currently being updated so hopefully that feature will be included. Also, note that the metronome is only available in standalone mode (in the Petrucci plugin).
Sure! Unless they removed it for some reason etc., I would email support@neuraldsp.com and inquire about the metronome and point out it was shown in a previous manual.
