My client sent me a warning she received from QB when she opened it yesterday that she needs to update to the latest release prior to 05/31/18 to ensure uninterrupted QB services, and to run the TLS 1.2 Readiness tool from a QB artidle to confirm her system is TLS 1.2 ready. She is in version 2016, so this doesn't relate to them discontinuing their support of version 2015. I told her it would be OK to update to the latest release when asked, but as for the TLS part, she should talk to her tech guy. Has anyone else seen this? What is TLS?
