When Harmony compares releases with incompatible track lists for a given provider URL or barcode it may show the infamous Providers have returned incompatible track lists error.
It would be useful being able to see the releases that were compared so the offending releases can be manually added.
Example:
https://harmony.pulsewidth.org.uk/release?gtin=®ion=us&category=all&url=https%3A%2F%2Fwww.beatport.com%2Frelease%2Fdo-you-love-me%2F4986503
