So when my old job had it, about 5 (out of 30) people in my area just couldn't open it.

Not the same five, IT would frequently reinstall it to fix it, but it would just break constantly.

Work computers, very locked down, couldn't do any alternative to it at the time, and we worked remote, so while everyone else had chat, some unfortunate people needed constant updates via email.

The question was who would be SOL, not if someone would be, that day.
