Most loading issues clear with a few quick steps:
Refresh the page and make sure you're on a current browser (Chrome, Safari, Edge, or Firefox).
Check your internet connection — the 3D view needs a steady connection.
Sign out and back in at app.tryinhouse.com.
Try another device or browser, and disable ad blockers/VPNs if the page stays blank.
Note: if you just requested your twin, it may not be ready yet — most arrive within a few days (see "How long does it take to get my Digital Twin?"). If it still won't load, seems stuck, or it's been longer than a few days, contact us with your account email and we'll check on it.
