We have Sage 300 2020 update 2 and our Avalara plugin won't connect to the sandbox envionmnet (but it does connect to production). It appears to be because the Avalara Sandbox requires TLS 1.2 (but production doesn't until the end of this month).
My question is whether Sage 300 2020 update 2 "supports TLS 1.2" for outgoing connections from plugins that presumably use their SDK. And if not, what version do we need?
We have the latest Avalara developed integration installed, on Windows Server 2016, and have verified that TLS 1.2 works from other applications.
