I realize MrBazar already posted a question with a similar thread title but my issue is different. When I try to login to my YouTube account on my Hero it tells me "There was a network error while trying to sign in to ******..." etc. I've tried several times, double-checked my account name and password on my pc, and even successfully logged in via the Browser. Any thoughts as to what this issue could be? Alternative apps would also be nice to hear about.
