No graph data on my My IBBQ-4T

Help I really need graph history and it has not been showing for almost a week…

Hello,
Sorry for the inconvenience.
Please update the app to the latest version and refresh the chart function. Does it work?
If it still has problems, please email the country, phone model and product device ID to support@inkbird.com.
