Hi @bisconne,
Thanks for flagging this. I understand how handy that shortcut was in your workflow. Could you please try using Ctrl + Alt + ' (Windows) or Cmd + Option + ' (Mac) and let me know if that brings up the Baseline Grid settings for you? Just a heads-up, make sure your zoom level in InDesign is set to at least 75%, the grid only becomes visible above that level.. Reference:
I'd love to hear if that works or if you're still seeing the issue, and I can check with the team further if needed.
Looking forward to your update.
Abhishek
