That's somewhat funny, for me, all AND segments are broken. I must edit and save them, then they work for the current session. After logout/login it's gonna be broken again.

Simple example:

Error: The segment 'referrerType%3D%3Dcampaign%3BreferrerName%3D%3DGOOGLE' is not valid.

Which browsers are you using? Can you reproduce that behavior in another browser?

I tried Firefox and Vivaldi. Same result.

I did a short test.
My segment is a long list of "or" statements.
Chrome is showing no accesses when selecting the segment. After editing the segment, correct accesses are shown.
Internet Explorer is showing all accesses after selecting the segment. After editing, it is showing some errors.

After editing I got an error, too:

Chromium, Firefox, Opera, Vivaldi and Otter on Linux.

this is probably not a problem of AND/OR but filtering for operating systems or device types in general! Device-Type-Filtering works for me but filtering for operating system does not: see: #11321

I don't think so. My filter rule is simple, contains no operating system and filters only a certain campain and fails.

It may be related to #11321

@tsteur Yes, that's possible.

Should be duplicate of #11321
