@ega Hello Ega. After a few days of testing, I think we found the root caused for the problem. I believe if our router was set to use with cloudflare DNS (1.1.1.1), then this will reproduce the error, which is the time series charts and apex charts could not update from the data bucket automatically. Could you try out with this DNS setup??
It is a very weird behaviour, I use the Google DNS (8.8.8.8 and 8.8.4.4) in my router and have had no issues, but for sure will try your setup in order to reproduce the situation and let you know the results.
