I am in Wadrium. You need seven blue shields/diamonds to proceed to the next world. I confirm that I have collected all seven. I’ve even watched walk-through videos. All seven of the gray circles where the seven blue shield appear I have collected. But, somewhere along the way, one went missing from what I've collected so I cannot complete the portal to the next world. I know it’s a glitch. I clicked on the support button in the app and explain my issue but haven’t heard back and it’s been a couple of weeks. Does anyone else have a resolution for this?
