Does your key also have FIDO2 as well as FIDO?

If your key supports U2F, it should be backward compatible if it support CTAP2.

Is FIDO2 backwards-compatible with current YubiKey models?
The WebAuthn component of FIDO2 is backwards-compatible with FIDO U2F authenticators via the CTAP1 protocol in the WebAuthn specifications. This means that all previously certified FIDO U2F Security Keys and YubiKeys will continue to work as a second-factor authentication login experience with web browsers and online services supporting WebAuthn.
The new FIDO2 passwordless experience will require the additional functionally of CTAP2, which is currently only offered in the new Security Key by Yubico. CTAP2 is not supported in previous FIDO U2F Security Keys, or current YubiKey 4 series, or the YubiKey NEO.
It sounds like perhaps your Security Key is the older version. On the other hand, according to the second paragraph, my Yubikey 4 shouldn't work either, but I was able to update my credentials with Fastmail.
