It does seem the business requirement for real-time is often ignored in "offline first" write-ups. If the current, up-to-the-second status of a server is being monitored, if vital signs for a patient are being monitored, etc., an app only delivers value if it provides the "now"/real-time data. Some form of websocket calls will be used, not Ajax. Showing something from the past because the data was stored locally is not helpful in assessing the current, real-time condition. There may be some things you can do to cater to the condition of being offline, but the point remains this app delivers almost zero business value while offline.
