Mine is not working either. Spent 15+ hours on phone with cell provider Samsung and yahoo support by email since they evidentially discontinuedphone support, just to find out my mail doesn't work on my tablet either. So android or yahoo problem
hmmm. I don't think it's android, because I tried Gmail and it worked. It has to be Yahoo. I hope it doesn't go on for days. It not been working via IMAP or POP all day today. However, using it via the browser works.
