VSMac 2019 version 8.5 is too buggy to use. How do I downgrade to a previous version? I have seen too much time searching for the answer on Microsoft's mess of a website and when I try and get an answer from support I am blocked by a pay wall that wants to change me $500 to simply connect with support. All I need to do is downgrade, but Microsoft seems to have hidden that information. Please help.
