I see two translation bugs:
eM often doesn’t detect that there’s a foreign language. Is there some way to force it to translate? It’s strange that it often can’t detect messages that are 100% Japanese. And sometimes I receive emails that are partly English and partly Japanese – it would be great to have a way to force it to translate the entire message into English.
After I translate a message “now”, there’s often no way to go back to the original message (“Show original” does not appear) unless I restart eM Client. And often after restarting, eM no longer detects that the exact same message can be translated and shows no translation options at the top at all. No idea why it would detect a message in a foreign language properly once, then not detect the same message after a restart.
