"Add to library" button not active

As in subject - while playing Tidal tracks the “Add to library” button is greyed out.

Welcome to the Roon community, @Michal_Potok.

Thank you for the report. I believe this issues is identified and on Roon’s radar.

Workaround:
“Add to library” still works on Roon Remote (Android).

When will this bug be fixed?
