Plex Connecting with sonic transport

I am using sonic transporter as my server . It has worked well with Plex but when I went to update it by deleting and reinstalling there have been a couple of issues. All the data uploaded but I am getting a message “sonictransport is currently unavailable retry connection” Tried troubleshooting but it won’t Clear it. It is next to home videos and playlists. The other issue is on plex Amps there are two libraries, Sonictransport & MacBook Pro. Will the plex amp play both now and I need to choose which ?
