Third-party cookies now required?

I’ve started getting errors that third-party cookies must be enabled in order to upload papers to Paperpile. I don’t recall changing relevant settings.

Am I correct that Paperpile has recently started requiring third-party cookies? If so, what is the purpose of these third-party cookies?

Apologies for the delay here, Reece. Has this continued happening? No updated requirements on our end as far as I know, but if you’re still getting the error it would be great if you could share some screenshots for the team to investigate. Let me know.
