Issue with Accessing Beta Version via TestFlight

Hello,

I attempted to install the Beta/Gamma version of Shapr3D via the provided TestFlight link, but I encountered the following error: “Beta Not Found. There is a problem with the public link URL.”

Could you please clarify:
1. Is the link still valid?
2. If it is outdated, could I receive an updated link to participate in the beta testing?

Device used: iPad.

Thank you in advance for your assistance!
