There’s a Snowflake, oops, Facebook group or nine for DNA test discussions related to genealogy, lots of incredulity about how their Warren family relatives (ahem) didn’t show up on the test. No free tuition for you, hah! :^)
My results matched the paperwork, other than the previously unknowable archaic DNA info.
My results matched my non id info spot on. It also verified my biological family on both sides. In fact my highest match was maternal first cousin.
