Ipad proxy keeps logging off

Hi, I am having an issue where if I try to download PDFs to my iPad version of paperpile, it says “proxy connection failed.” I log in to the proxy again, but it keeps kicking me off the proxy and saying it failed. My proxy is University of Cambridge. Any help would be appreciated!

Apologies for the delay getting back to you here, @Christiana_Scheib. Please let me know if you continued experiencing proxy connection issues in the mobile app and I can reach out to the team for support - here or via chat/email (support@paperpile.com).
