I keep getting the message that I need to renew authorization....so I followed instructions and signed in with ebay....it then says that authorization was successful, but when I try to set the snipe, I get the same error message again....I tried using two different browsers and even two different computers but nothing helps.

Hello Chris,
Thank you for your question about your authorization. We just updated it manually for you, because your account was created before a certain software update we issued in February 2020.

If the above does not resolve your issue, please let us know, and we can take the next step. Thank you for taking the time to write in.
