I am having the same problem as others with entering bills against P.O.'s. The list of P.O.'s as well as the list of item receipts comes up as options to post bills against. Sometimes the P.O. that I need is not listed at all! On top of that, when I try to start a question in the help window on Quickbooks, as soon as I start to type the window shrinks. Over and over. Also am unable to email from the Customer Center. All of these problems have started since we updated to 2021. Very frustrating.
