Yes, I confirmed last night that Settings -> Google -> COVID-19 Exposure Notifications was off. (Aside, I read somewhere but have not confirmed this myself that manually enabling that setting leads to a flow for installing the gov.ma.covid19.exposurenotifications app, whereas the forced update is gov.ma.covid19.exposurenotifications.v3 -- note the extra v3). By the way, MassNotify app is not visible from Play Store search (both on mobile and on desktop -- https://play.google.com/store/search?q=MassNotify) and does not create an icon -- you can only find it in Play Store via its internal name (e.g. a link like https://play.google.com/store/apps/details?id=gov.ma.covid19...), and would have to specifically look in system dialog for all apps to see if it is installed.
