You used to be able to hover your mouse over a paragraph style in the paragraph style panel that had an override (plus sign). When you hovered over this style it would display a tool tip showing you what was overriding that style. This no longer works.
InDesign magazine has even written an article about it... https://indesignsecrets.com/how-to-get-tooltips-working-again.php
The only way to fix this problem is to resize the panel. Every time you need to see what is overriding a style you have to resize the panel meaning you may have to resize the panel dozens of times for a document.
Please fix this. I can’t believe that this is not already on here.
