It is as if it disappeared into thin air. All of the functions that I paid for, before the update are now behind a subscription wall. Some might call this a rip off! Maybe some form of bait and switch. Unfortunately this has happened to me before on other apps, and has become a pattern for some time. If you, developers, are going to conduct business like this, at least have the dignity to warn the costumer before the update! Do you have any dignity? **Developer response:** Hi, We’re truly sorry for the issue and understand how frustrating this must be. Your lifetime purchase should not simply disappear. Please try tapping “Restore Purchase” on the paywall. This should restore your lifetime access. If you still have any issues, please contact us through Settings → Support or email [yusuf@onnex.co] with your User ID. We’ll look into it and resolve the issue as quickly as possible. We’re always here to support our users. Thank you for your patience, and we sincerely apologize again. ### 5/5 — Samuel *2026-08-03* Fellhauers ## Frequently asked questions about STL & 3D Model Viewer ### What 3D file formats does Mes3D support?
