Glad to hear that resetting the DSP allowed the EQ to show up again. I believe you may have accidentally removed the EQ so if this occurs again you can press on “Add Filter” to add it back to Roon. Also, we have just released Roon build 416 which addresses the issue of additional DSP toggles on iPhone. iOS builds are still being approved by Apple at this time and should appear soon.
