Have a fully functioning UN in a fgdb and trying to copy/paste to SDE. Receiving the error below:
Failed to Paste. Must be connected and signed into the portal.
UN v6. Pro 3.1.4 SDE 3.1.4 dataowner access: correct.
Have tried copy/pasting other things into same SDE. Works fine. Only struggles with UN. Test copy/pasted UN to another fgdb - works fine.
Have removed and readded portal. Error remains.

Anyone else experiencing this behavior?
