I tried my luck with that too, trying to upload my iCloud library from my Mac to google photos. It is a giant pile of shit. I went ahead and wrote a simple app that reads iCloud metadata and uploads directly to Google Photos API. It synced everything in a day. I dont understand how did they manage to mess this up so bad.
