@juraj - I'm having this problem with a one way staging synch. It seems to be affecting many documents.
For one example document, in the dev environment the details are:
Node ID: 10393
Page ID: 10374
Node GUID: 03f5f36e-6b17-4934-8340-0681fd8e6ced
Page GUID: f4a5e798-60e7-4ebb-a1cc-5238cca7947d
and for the same document in test, the details are:
Node ID: 10414
Page ID: 10400
Node GUID: 03f5f36e-6b17-4934-8340-0681fd8e6ced
Page GUID: f4a5e798-60e7-4ebb-a1cc-5238cca7947d
Should I expect that the Node ID and Page ID are the same between both instances? Or does staging use the GUID to identify the items?
