Have struggled through this and think my answers must be right but would love some help parsing a couple of them:
14d We're not enjoying this first sign of love in heart of sycophant(10). Taking sycophant as the definition, and with the other letters I've got, I've got a synonym beginning with B, but haven't a clue why.
22d Polish side-switching is repellent. As above I've got an answer that fits and means repellent, but no idea why.
Like others I can find only 5 undefined clues, three down and two across
