Since Axiv is open access shouldn’t reroute via proxy, doing so will actually result in error:
Paperpile already can tell if a link is axiv, it should also exclude these from using proxy, or allow users to set up some domain to exclude.
Thanks for this bug report, @Emrick. The team is aware of it and it will be fixed in a future release of the new app. Rather than reporting these issues as new topics on the forum, please report them via the in-app chat, email us at support@paperpile.com, or you can add them to the new Paperpile topic.
