Install problems that disappear in a private window are often cache problems. Marketing teams add the snippet; CDN still serves pre-install HTML to everyone else.
Purge and verify
- Identify your cache layer — Cloudflare, Fastly, WP plugin, Vercel, etc.
- Purge full-page HTML for the site or the specific URL you test
- Open a private browser window and load the live connected domain
- View Page Source and search for the Amevia install tag
- Run Recheck installation in Amevia Installation
Still cached
- Purge twice if your host has edge and origin tiers
- Query-string cache bust (?v=2) helps debug but fix the real purge before go-live
- Service workers can cache old assets — unregister during testing if you use a PWA
