Yes, I think my choice to set temporary citations preferences to use the Pages field instead of record number is non-ideal, because not all records have Pages and I wonder if the field changes between record types. However, the default of using Record number doesn’t work if you’re trying to write a collaborative manuscript and different authors are inserting citations, since obviously the Record Number is different in each library. However, I gave up and insist on managing the citations and bibliography in jointly authored papers. EndNote really doesn’t play well in a distributed OneDrive etc. environment, as you’ve noted elsewhere on this forum. I’m not sure the problem is entirely with EndNote’s structure, as the problem I see is each author builds their library differently which results in inconsistency. That’s an issue whether it’s EndNote, Zotero, Mendeley, or the rest.
