Not the same, but this still doesn't explain why Apple Photos is so dog slow and has so few indicators as to what's going on.

Apple Photos: Uploads stuck? Check. Sharing photos taking up to three hours to show up on the other person's device? Check. Weird formats when sharing (qt/mp4, downsized jpegs/pngs/hvecs) with no controls? Check. And so on and so on.

Google Photos has its quirks. But man is experience so much better.
