Seed phrase unavailable — hardware wallet 2020

Blocked
Case description
A user who had split their seed phrase into two halves and stored each half at a different location found in September 2020 that one location — a rented storage unit — had been auctioned off by the storage company for non-payment of fees. The tenant (the user's relative) had not informed them. The auction buyer discarded the envelope.
