Staking rewards on Luna Classic often include a variety of coins from the network. One of them, UOSMO, is unrecognized by Koinly. I believe this error is terminating the sync prematurely; no transactions after March 2, 2023 will import. (I was receiving the same error with the UATOM coin also, but now it’s just UOSMO.) The error message is Currency not found {:symbol=>“UOSMO”}.
I am using Terra Station and syncing via the Terra Classic API. I’ve tried resyncing (multiple times), deleting the wallet and re-adding it, syncing starting at a date after the appearance of the UOSMO coin.
