Decent isn't good enough though. It runs slowly, meetings lag periodically (at least on Mac), and the "everything else" is the part that is mandatory (accessing and reviewing assignments with my kids at school, accessing and collaborating on documents, etc).

I have lost track of the number of times we bailed on Teams for even meetings when interacting with teachers or the other organizations I work with (as a volunteer which makes the tooling issues even more frustrating), in favour of another service, or collaborating in a google doc instead.
