I am experiencing a similar problem.
I am no longer able to send emails from my mobile (Android) @uol.com.br account to Evernote. I don't receive any error messages, but the emails never arrive in Evernote.
However, the same account @uol.com.br works perfectly from the PC (Windows). Because my other e-mail accounts remain working properly, it is not a cell phone configuration issue, but rather an EN bug.
I have sent a message to Evernote support.
Any suggestions to solve this issue?
Thanks!!!
