Hello @Scott_edwards, and welcome to the community! Generally we see issues like this for a few different reasons. Can you elaborate on your network setup for me? Also, does it always get stuck on file 2?
If so, there might be something wrong with the track in question. If you can get it to stick on that file again please reply here with a timestamp (your local time) of when it got stuck! We can enable diagnostics for your account and see what’s going on with that track. Thanks!
