I have a Model-driven PowerApp where I have created a pie-chart to show alongside the list of my table content. I want to change the colors used in the pie chart, and based on Using Custom Colors in Charts | crm chart guy (wordpress.com) I have edited the XML-file for the chart. Specifically, I have done these modifications:
<presentationdescription>
<Chart Palette="None" PaletteCustomColors="#8ECDC8;#B7ADA5;#4099DA;">
<Series>
But the colors do not show up in the UI.
I have made the changes to the XML in "Classic interface" and done a "Publish All Customizations" from there:

I have also done a "Publish all customizations" in make.powerapps.com for my model-driven solution:

If I open the Chart in the "editor" for the model-driven app, it shows the colors nicely:

But if I open the app itself (by choosing "Play" or accessing it directly via the URL), the old colours are still displayed:

When I export the Chart as shown below - I can see that the new colours are ind the export, so it somehow loads the correct file - but does not show the correct colours.


I have done multiple refreshes (including enabling "developer mode (F12)" and doing a "Empty cache and refresh" in Edge, but nothing works.
How do I make it show the right colours?
Thanks 😊
