Getting the same issue in chrome and safari both.
Topic summary
Site content loads and then disappears, especially on mobile, with issues also seen when editing the site in the backend. Affects Safari and Chrome, with Chrome occasionally loading correctly but inconsistently.
Clearing cache and browsing history did not help. Multiple users on different devices and both browsers confirmed the same behavior.
The reported fix was to update the Shopify theme to the latest version. After updating the theme version, the disappearing-content issue stopped.
Status: Resolved by a theme update. Recommended action for others experiencing this: update the Shopify theme to its latest release.
