In the latest Salesforce update you can no longer use ISCHANGED along with the Advanced checkbox in Process Builder. (Also does anyone know where there is documentation about this change?)
I am trying to figure out how to trigger a time delayed process when a field changes. The field might not necessary go from null to not null, but from one value to a different value.
(There is the work around of using a formula instead.)
I am nearly positive you could.
I had read that part of the release notes before and they touch on both ISCHANGED and the Advance checkbox, but not their intersection/use together. So this still seems completely undocumented to me.
I will test out your relative date filters, but that still seems like a work around to a pretty basic request which is only trigger a time delay process when one field changes.
