Lost my unlocked priveleges – Sudoku of the Day Review

I enjoyed OTD for a couple months after upgrading from the old AW Sudoku; some things were better (could always get the day's puzzles if I had a connection), some worse (pencilmarks contrast). However, today it started showing ads. Restore purchases requests iTunes passwd but then just sits there. Banner ads really wreck the game for me. Ponied up another 3 bucks to get back to scratch, but very frustrated about the backsliding to annoying ads.
