Anyone have any issues with customfields not showing up in saved searches or the global search, even though the custom field is set to be globally searchable?

I've occasionally had them get "stuck" in the short term. Usually if you log out/back in and/or clear your cache, they'll show up.

I e experienced this too. You can also do a formula text and add the field Id as the formula. Kind of a workaround but gets the job done

AI1, the issue has been classified as a defect, however its set to U7 status, which means they will not do anything about it. If you submit a ticket for this they will bump it to U6 and will then fix it.

I will try to find an example of this and submit a case as well

Thank you!
