Do Not Track Cookie not working

Hi. I’m testing the Do Not Track option Matomo provides. I incrusted the iframe into my website and when I uncheck the option for not being tracked, I’m still being tracked. The piwik_ignore cookie is created, but it seems like it is not being used.
I tested it with a Matomo 3.2.0 and with a Matomo 3.5.1
I also made the test with Chrome and Firefox.

I really hope you can help me.

Thank you very much

You are aware of the fact that your browser will still send the requests to Matomo but these will be ignored?

That’s the thing, Matomo is not ignoring the requests, it is counting and processing as usual.
