Hello @Smiles8, Welcome back to our friendly King Community
Sometimes, clearing the cache and rebooting our device would work to bring out the Trophy, but not all the time!!
Since you are on iPad, try to play couple of levels and exit to the Map screen. Now, the "Trophy" icon might pop-up!! I tried it yesterday, and the trophy reappeared for me
Please let me know if I can be of further assistance! Have a wonderful day/evening!
