EDIT: The logo has appeared again but still does not do anyting when clicked on.
I have been using this plugin for a good couple months now and only just now ran into this issue. I used to have the Equalify logo at the top left as always, except today I suddenly do not have the option to open it. It started with the logo being visible, but me clicking on it caused nothing to happen. I restarted Spotify only for the Equalify logo to disappear entirely! I am not sure if Spotify recently updated, but it is currently running on version 188.8.131.524.gac68a2b3 . I am also not running on the Windows Store version.
If anyone ran into this issue and found a work around, I’d love to hear it!
