[Star Wars] Why don't the Inquisitors use tracking fobs to find the Jedi, like the Mandalorian uses to find bounty targets?

I don't think we have enough info on how the Tracking Fobs work right now or the limitations of them. 

We know the Tracking Fobs are tuned in to a target's chain code somehow. Maybe Jedi just didn't let themselves get signed up for the chain code? Maybe the Jedi used forged chain codes. (That has been done) We can just guess right now.

Not having a chain code would disallow a Jedi from using commercial travel from planet to planet, but it seems like Jedi-in-hiding are using backdoor methods of getting around.
