Not sure if this needs to be a feature request - but feels more like a bug.
On my map, I have 3 groups, each with a custom colour I have assigned it (say red orange green).
This works fine. But at certain times of day not all 3 groups will appear in the dataset.
If I have a dashboard on screen on a timed refresh, if one of the groups drops out, when it reappears it adopts a new colour altogether. Blue, in my case.
If I do a refresh of the actual web page URL (or open the same dasboard on another tab), it’ll revert back to my custom colours, but the scheduled refresh alone isn’t correcting the colours.
