System UI Tuner

[barryb1975]

Hi all, I'm unable to access the System UI Tuner on marshmallow.

I have an HTC One M8.

I've tried all suggested attempts to unlock it I.e ensure animations are on, ensure developer settings is on. I've restarted numerous times but it's stubbornly remaining locked.

Has HTC removed it?

Thanks

Have you long-pressed the Settings "gear" in the notification bar?

Yes, I pull down the slider menu and long press the gear wheel.

I've tried it numerous times.

Any ideas?

I'm not sure about the M8 but other HTC models didn't include the UI tuner after MM.
