Is this happening to anyone else? – Dig Tycoon - Idle Game Review

I downloaded yesterday and I have lots of buildings built already. It is pretty cool if you like idle games. The only problem I have found and idk if it’s the game or just my phone, but I can only collect gems from the first building. I can’t collect any other gems and it is sad because I need gems to hire better people. I can’t go to far without being able to collect gems
