If I lookup a key on the key oxide site via WKD (
https://keyoxide.org/wkd/<email>), it finds my key using WKD.
But if I then do "Encrypt Message", when trying to subsequently encrypt, an error:
Could not encrypt message!
Public key could not be fetched (Misformed armored text)
I suspect the problem is that it is attempting to to HKP lookup instead of using the key just retrieved by WKD.
(In the case above, the key is only available via WKD and not HKP).
