Unit4 Tasks

Invalid date

- Push notifications are now triggered automatically to alert users when new tasks are assigned.
- We have introduced a notification badge that informs you about new tasks assigned so that none of them are left unnoticed or unreviewed.
- We have fixed an issue that caused an error to appear when you tried to approve invoices from a different client than the one where they were created, and the tax system or tax code existed only in one of these clients.
