There are many services out there which are confusing users with wrong information. Is not about not knowing it needs to be in hex.

I found one that says "Some clients may not recognise your public key as used above and you may have to use your npub key instead".

Unfortunatelly apps are not converting to hex anymore (IMO it could appear in the profile) and https://damus.io/key/ is a rare exception. Other sites that said they would convert (in some documentation) doesn't do that anymore.
