Dear Sandbox Users,
There is currently a small bug where users are seeing the "Estimated Setup Time" during lab setup match the overall reservation duration. This is harmless and your lab should only take 30-60 minutes to set up. We currently are working on this issue and hope to have it resolved in the next day or so. We will reply to this thread with updates.
Please let us know if you have any questions or concerns.
Thanks!
DevNet Sandbox Team
