During start-up, a default Ofono context is set as soon as LTE is attached : defaut public APN is then recorded. How then context must be handle to change it with another private APN authenticated with user, password ? I tried to change it dynamically with dbus (AccessPointName, Username, Password) but error message "The resource is currently in use" is returned Ofono 1.24 Modem Quectel EC25
