Popup Notices
Please stop having popup windows when I open Acrobat. If I just opened a file, it is because I am working. The popup is very irritating. I understand that you are trying to tell me about a feature, but the timing is horrible. There is a notification bell - please use that for announcing features.
Also, it shakes my trust in Adobe to have to go through so much effort to give feedback. The account creation process is absurd. I understand that you have to accommodate the bad actors in the world, but the burden can't be just transferred to users - especially for a site that really needs so little security. I do appreciate that you validate email addresses though.
