Horrible app. 10-20 secs to load. Menu bar has forward button but no reply (you have to click on "More.") IMHO, replying to email is done more often than forwarding. Open app & Inbox shows X unread mail. But no new mail is in inbox. Click "Unread" and it shows no unread mail. Return to Inbox and it shows 0 unread. Go to another folder then back to Inbox & it shows X unread mail. Error trying to create new filter or change existing filter. Spam mail has to be opened to see actual sender address.
