Any update on the issue of the Paperpile button not appearing in Google Scholar search result page?
I am trying to use the Paperpile extesion on Chrome on my new Windows 11 PC, and am experincing this same problem. When I restarted the extension by switching the it off and on in the Chrome menu, the buttons actually appear on the search result page, but when I reload the same page, the buttons disappear. Exactly the same symptom with PubMed. I tried restarting the browser, signing out and back in of my Google account, and clearing cache and cookies, but the problem persists.
I never had this problem on my other PCs (Windows 10).
PS I rebooted the PC, and the problem seems to have disappeared!
