Hi, I've been experiencing this problem for a while now. I've tried all the solutions I've found in the community forums and adobe's support pages (adobe creative cloud cleaner, LAN settings, uninstall and reinstall, host files, etc.) and nothing has worked for me. The license that the apps are connected to are my school email, but it is expiring soon. Yesterday, I bought a plan on my own email (the one I'm using), but I am unable to open Creative Cloud to switch my accounts. When I tried to contact the support chat, it says that the account I'm using now does not have any registered product so I don't know what to do. Is there any other ways I can fix this issue? Much appreciated!!
Thanks so much kglad! I finally realised where my mistake lies. I initially only cleaned the Creative Cloud desktop app, which wasn't enough to fix the issue. So I cleaned all "CC Apps" and followed the same instructions, and now everything is working again. Really grateful for your help!!
