The help page on Preprints (https://help.researchgate.net/hc/en-us/articles/14293104044177-Preprints) contains a link to the Copyright section (https://help.researchgate.net/hc/en-us/articles/14295302418321). When I follow this link, it redirects to a login page. Clicking on "Switch to agent sign-in" leads to the page https://researchgatesupport.zendesk.com/auth/v2/login/signin?role=agent. This site does not accept my ResearchGate login credentials. Do others have the same problem? Previously I did not have problems to access the Copyright page directly.
