GivTCP and ApexChart not displaying previous days sensor data

Hi All
Looking for some help please, troubleshooting an issue with GivTCP and displaying previous days data in a chart.

I’ve got a basic Apex chart what I’ve had setup working for months, it shows the energy I’ve imported from the grid and the PV generated per 24hrs (1day) over a 6 day rolling window.

As I said this has been working fine for months but recently it will show no value for previous days, e.g. it will show data for today (currant day) then at midnight it will show that value as 0 for yesterday. Sorry may not have explained that well so maybe the screenshot will make it clear!

I don’t think the issue is with HA recording the data as if I look at the history on the sensors, I have data over the last few days.

Also to rule out Apex being the issue I get the same problem with a Statistics graph card.

I’ve got the issue on mobile, tablet and browser so don’t think it’s a cache issue.
Running HA as a VM version core 2024.4.2

Any help appreciated
