How to fix button triggers after upgrade to 5.2.3f1 Personal

I just upgraded to 5.2.3f1 personal from an earlier 5.x version and now my button triggers aren’t firing. The button transition animations are displaying on mouseover and mouse up/down, but Pointer Down and Pointer Click triggers aren’t executing the scripts they’re associated with. This was working before the upgrade.

Is there any input setting I need to check that may have been reset after upgrading?

I figured it out. I had to check the box “Force Module Active” in the Standalone Input Model component on the EventSystem object. It must be an issue of mouse vs touch, but for some reason it wasn’t necessary to check this box before. I confirmed that touch still works with this checked.
