I have just realized that the whole year 2021 is missing from my transaction history. I can see the transactions in the chart when I hover the mouse over it, but not in the history.
I realized it only now, because I uploaded the Trezor history to the CoinTracking tool and it shows a lot of missing transactions. And by tracing some of them via Blockexplorer I realized that they went to my Trezor.
Is it possible that these transactions were made from a different account? If so, please keep in mind that transaction history is always connected to the account that was used for sending (receiving) the transaction.
