I’ve noticed that when a paper comes up in a Pubmed Search that I already have added to my Paperpile library, the “Add to Paperpile” button is still active. I am not getting this problem on Google Scholar though. Chrome is up to date (Version 84.0.4147.105 (Official Build) (64-bit)) and Paperpile is up to date (Version 1.5.148).
I’ve also been getting failures after clicking Add to Paperpile on Pubmed. Sometimes reloading paperpile and the browser page works, sometimes it does not.
