Let me know my account doesn’t have access instead of a 404

Trying to access some photos on Google Photos as per Do you manage your photos? but I’ve got a 404:

Figure: The photos existed but the message tells me otherwise

We later realized I was using a wrong account (login).

At first, I didn’t even think about changing accounts because I got a 404. Instead, we would expect to see a message like:

You have no permissions to see these photos.
