Hello Miss Barbara and Miss Kathy and LDW friends!

I’m so excited to finally be playing VF3 on my iPad! I’m on the 3rd generation and purchased the Rockhound Certificate from the Store. Unfortunately, I am only able to dig on an indicated spot successfully about 1 in 12 times no matter how many times I drop one of my peeps on it. I’ve tried using different people in the family and even resetting my game. Immediately after purchase of the certificate they were able to dig after dropping them on the spot once. Now I can drop, and drop, and drop them and nothing. Is there something new I’m missing-like a next level certificate or something for certain spots? Wondering if anyone else has experienced this issue?
