We have a good reason to believe that instagram is testing out new features on some posts and those posts don’t seem compatible with our system.
We are working on a hotfix to support this new format and in the meantime, please try to use the free option to verify if your post loads before unlocking.
We are sorry for the inconvenience and if you experienced this issue and have paid for the service, please use PayPal to request a refund and we will approve it from our side.
We apologize for the inconvenience caused by this event and we are working hard to resolve it.
Thank you for your understanding!
