I am currently using the trial version of the pro/ent version. I have it working on Ubuntu 16.04.5 and Unifi Controller 5.8.30. So far so good.
One thing I can't figure out is how the QR is supposed to work:
1) Once the login pages shows up, switching to a QR-reader disconnects from the spotipo guest network. I have seen this on ios.
2) When you scan the QR code manually, it takes you (as of 09/26/2018) to this forum, I am missing anything?
