For many years, I've assigned my own keyboards shortcuts to Microsoft PowerPoint. (Note: this is a built-in feature in Mac OS, not a 3rd party solution).
Since the latest upgrade to PowerPoint 16.27, these shortcuts stopped working. Nothing else on my system has changed – same MacOS version, same everything.
This has a huge impact on productivity. (I work as a designer, and shortcuts for "group", "ungroup", "align top" or "distribute horizontally").
It'd be great if you could investigate on this. On previous PowerPoint upgrades, and also after MacOS system upgrades, this never was a problem.
