To be more specific, are you opening Roon mobile for the first time? Or, was the app already open and you’re bringing it back up?
From your account admin, it doesnt look like your iOS device has communicated with our servers in around 2-weeks. Could you please use the directions found here and send over a set of iOS mobile Roon logs to our File Uploader? Once logs have been uploaded, please let us know so that we can check the server for your files, thanks!
In the meantime, if you haven’t recently, I’d also stop Roon Server from running on your Mac, and reboot the machine as well, and let me know if you run into the same issue.
