I have been receiving this error on gummy drop but only on one purchase. I have asked all involved parties for a resolution but each one blames the other.
I am sorry to hear you are still experiencing difficulties with your purchase on Gummy Drop. Unfortunately, this is a third-party application.
I recommend contacting the Gummy Drop support team directly. They will be able to investigate the error with your purchase and provide you with the most appropriate assistance. You can find their contact information typically in the app’s settings, on their official website, or through their social media channels.
