I downloaded YMail from Sprint a week or two ago and it's been working great ($2.99/mo.). It pushes all my email to my Treo and alerts me.

Yesterday (11/22) it stopped working. It still alerts me I have new mail but when I open the application my inbox is empty. I tried re-downloading it and no luck. I try manually syncing and nothing happens. Last night when I got home I had 23 unread emails in my Yahoo inbox.

I am frustrated. Anybody else have this problem??
