I found the first easter egg for the 2023 Easter Egg Hunt event, but when I redeemed the prize, I didn't get a clue as to where the next egg will be, and I can't go and re-find the egg, and I can't do anything with the prize I received, but when I go back to the Easter Egg Hunt Even clue list, the second clue doesn't appear.

So looking at the Egg Hunt atm, it's showing as you not having found any of the Easter Eggs yet.

Is it possible you are confusing the Easter Egg pop-up with the ones you have to find through the Egg Hunt? The Egg Hunt Easter Eggs are all ones found while exploring. If you're in Viridian Meadows or Umbra Forest, they'll be from battling in the correct Zone. If you're in Astryl's Vale or the Lost Grove, you'll have to roam the Zone to physically find them hidden somewhere.

Ohhh, that definitely could be it! I found one sitting on my screen at the diamond shop because I thought thats what my first clue was talking about. Didnt realise they were in the Zones. Thank you!
