We have the Human Resources app installed in Microsoft Teams but the notifications to users have stopped working. We've checked everything mentioned in the documentation for the app on learn.microsoft.com/.../hr-admin-teams-leave-app
So within Human Resources the system parameter to enable them is on
It's also turned on on the individuals user options and the batch job 'Business events batch processor' is also running.
Any ideas what else needs to be checked or enabled please?
