Minor Bug (Smart Guides on/off)
When opening/creating a new document,
the View > Smart Guides will be checked on. But they are not actually on. You have to turn them on/off a couple times to actually get them working. At first I thought that they were altered or removed from the last update. Fortunately I figured it out!
I am closing the ticket due to lack of response.
Please get in touch with us at email@example.com or any of the other support channels – https://helpx.adobe.com/support.html . Please give a reference to this post so that we can identify you.
Since this is not a generic issue that we can reproduce at our end, we will need someone to look into your machine to figure out what is going on here.

I keep disabling Smart Guides - CTRL + U. First time I disable them, they remain enabled. Second time I disable them, they do actually switch off but then switch back on again when I relaunch Illustrator.
