I've tried to read the docs regarding cookies, but I'm having troubles wrapping my head around.
Basically, my use case is this - I have the Adobe Audience Manager platform that is writing data to an aam_something cookie and it's delivered to the same page where the utag is present as well. I want Tealium to read the data from that cookie - is that possible? Is it done with an extension? I know that Tealium can _write_ cookies, but can it read cookies from the other platform?

If the data is stored in a first party context relative to the page the user is on, you should be able to pick up that cookie value within the UDO, it'll be called:
So it'll be accessible in extensions as b["cp.aam_something"], and if you add the item to the UDO in TIQ, you'll be able to map it to other tags.
If the data is truly a third-party cookie, you won't be able to access it client-side because web security depends upon not being able to access cookies cross-site.
Hope that helps.
