Burndown doesn't show any event, log or changes

Question

After starting the sprint, the only event that I can see in the burndown is the one "Sprint start", it doesn't matter if I log work, close issues, open issues, change scope... Burndown doesn't reflect any of those changes. Am I missing something? Does it need time to refresh by itself? Is configured to track Time.

Thanks for your comments

Thanks Sateesh, the status of the issues are Resolved, work log done, if I look into the Issue detailes I can see clearly the remaining estimate, the logged time, everything... Is just all this information is not shown on the burndown chart

Also please check if there are any parallel sprints for the same project on a different agile board ?

Could you please check the board configuration at Board --> Configure board --> Estimations and share ?
Unfortunately , burn down will only be reflected at the time of story closure / resolution time.
