We’ve asked Engineering to provide a “Flush Known Metadata” for an item (aka. RESET / “Scan again as if new”) feature.
To date, they have not provided it because of the “Dance” workaround.
In their defense, Properly curated media, presented the first time, won’t mismatch and need “dancing”.
FWIW, I have 28,929 files indexed and not one of them has ever mismatched
A defacto “Must Have” tool for media is one like FileBot. It gets it done right painlessly because it does the validating, internet lookup, and even structure creation for you.
