@Anoop Krishna I think the second statement is true. Whenever I click the the button I have set, which runs the activity and fetches the value from a notification channel and from a DSS. It successfully displays the message intended. This section is inside a dynamic layout and has an an OnLoad event with a refresh-other section callback.
Whenever I refresh the application in the browser, the message disappears and I need to click the button again for it to load the message.
