Field Parameter Slicer Not Updating Matrix Visual After July 2025 Update

RaghavendraV I'm having this issue as well, and no solution (as everyone mentioned), but I do have a workaround that has allowed me to still use my matrix as intended. It's a bit clunky, but beats me having to refresh the entire report to default settings every time I want to switch dimensions.

When the matrix breaks and freezes, I re-select the dimension that it froze on and expand one of the rows. This allows me to switch the dimension and then I right-click on the matrix and collapse all fields.

Here you'll see my matrix broke when I tried to switch from Month to Media Channel (we should be able to expand these rows):

I went back and selected the Month dimension and the view is displaying as expected, with the options to expand:

Then I expand one of the rows and I am then able to switch to another dimension and get the view to update correctly. From there, I can just right-click on the matrix to collapse all fields. This seems to only break when I select a dimension that is also included as a row in my matrix.
