iCloud photos not downloading to Mac Photos 5.0
Photos I take on iPhone are automatically uploaded to iCloud photos. In mid February I lost a iPhone X - dropped off a boat at sea. It had several photos that had not uploaded to iCloud (out of range). Got a iPhone 11 Pro Max the next day, and its upload & download with iCloud is just fine. But Photos (5.0) on MacBook Pro (Catalina, updates kept current) hasn't dowloaded a single iCloud photo since then. Storage space is not a problem - iCloud has a more than 1 TB available and MacBook has 77 GB. How do I get Photos to resume downloading from iCloud?
