Exclude requests by custom dimension value


I would want to filter the matomo visits, by a value of a custom dimension, in my case, I want to ignore the visits with the value of the custom dimension 1: ‘true’.

I have found this post on the FAQ https://matomo.org/faq/how-to/how-do-i-exclude-specific-tracking-requests-in-matomo/

And im able to filter the visits for example with undefined uid. But when i try to filter by custom dimension, it didn’t work. I have tried with:
But none of them did the work.

Also if is possible i want to ignore both, “dimension1==true”, and “uid==”, can I achieve that with two lines of exclusions ?

Thanks in advance!! :slight_smile:
