Allow working offline in Workforce app

    In Product Plan

    For our fieldwork purposes it would be very useful to be able to keep using the workforce mobile app when being offline. We assign enumeration areas including building points to our fieldworkers to collect data on living accommodation vacancy. Our fieldworkers will be offline from time to time during fieldwork, but need to be able to choose their next assignment, register start and finish, and use an offline basemap in workforce while offline.
