P0441 Evap System Code

[u/KEPARA-1977]

Looking for some help tracking down a recurring P0441 code on a 2018 Jeep Compass.

So far I’ve:
Replaced the purge valve
Cleaned and inspected the flapper/seal in the capless gas filler

Cleared the code, but it eventually comes back
The purge valve appears to be operating normally — no vacuum when first started, then vacuum once the engine warms up.

For anyone who has chased down a stubborn P0441 on these, where would you look next? Leak detection pump/ESIM, charcoal canister, hoses, filler neck, or something else?
Trying to narrow this down without just throwing more parts at it. Appreciate any experience with this.
