sry if this is in the wrong place, ive never traded poe on here. i am guessing exalts are tracked and divines are used instead?

Nah they made a change to make exalts have far less utility (all major bench crafts use divines now) so divines became the main currency of poe.

wow so they just up and made a main currency suddenly worthless?

Basically that's what happened. I mean, exalts still have some cases where you can use them, but it's not even close to the pre 3.19 era.
