Similar to another poster above, I subscribed so I can have direct support on this issue. The support person told me that Evernote is aware of this problem and working to solve it. I went back to the web access account info, and switched to the "new" version (which I hate). Yes indeed, web access now works. But when I switched it back to "classic," it stopped working and I got the "oops" message. Sigh. I love classic and hate the new version. I see from PinkElephant that classic may no longer be supported. Yet, support tells me they are working on it. If I can't get classic to work, I may migrate to OneNote. i don't know. Ugh. P.S. Windows desktop has continued to work. But I don't like the interface.
