Bitmex API not importing trades

Describe the problem:
No trades are imported from Bitmex. Everything else seems to be working fine.

Which exchange/wallet is this regarding?
Bitmex

How did you import data into this wallet?
Via API key.

What have you tried to fix this so far?
Re-checked bitmex api key.

I have two accounts on Bitmex. On one, I use Bitcoin as collateral and data is imported fine by Koinly. On the other account, I use USDT as collateral, and Koinly imports nothing, not even the initial deposit.

Bitmex added USDT only a few months ago, so I assume, that Koinly has not yet upgraded their Bitmex client. But they should do that soon, as otherwise, I cannot export a full 2021 tax report.
