I had an adobe account as a student and wanted to cancel once I was no longer a student. I tried to uninstall the apps, but I can't even do this without logging in. You should not need to log in to simply uninstall apps that you no longer want/need.
When I open the creative cloud app to uninstall it says your apps are taking longer than usual to load. Relaunch creative cloud or restart computer and try again. No way to uninstall. Very frustrating
if that fails to help you cancel, using a browser that allows popups and cookies, contact adobe support by clicking here, https://helpx.adobe.com/contact.html?rghtup=autoOpen in the chat field (lower right), type AGENT be patient, it can take quite a while to reach a human
p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative. ie, double check for an employee badge if contacted in the forums and look for an adobe.com domain in the email address if you click reply to an email. then check again and be very suspicious. any other method of contacting (or offering to contact you) is almost certainly a scam, https://community.adobe.com/t5/using-the-community-discussions/staying-safe-in-the-adobe-support-com....
