Not too fussy until the previous answer is sorted out (10)
I believe the answer is:
uncritical
'sorted out' is the definition.
Both the answer and definition are adjectives. Perhaps there's a link between them I don't understand?
'not too fussy until the previous answer is' is the wordplay.
I cannot quite understand how this works, but
'not' could be 'un' (prefix meaning 'not') and 'un' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
'answer' could be 'a' (abbreviation eg in Q and A) and 'a' is found in the answer.
'is' could be 'ii' (more than one I) and 'ii' is found within the remaining letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for uncritical that I've seen is " Dangle and Sneer were not".)
