I edited a template but the storefront still shows the old version
This is expected caching behavior, not a bug — here's the timing and why product-level edits are different.
Template section edits can take roughly 1 to 6 minutes to appear on the storefront. That delay comes from CDN caching on the template lookup, which keeps the storefront fast for every shopper browsing your catalog at the same time.
Product-specific chart edits are different: they are never cached, so those changes should show up immediately after you save.
If a template edit still hasn't appeared after 6 minutes, double-check that you edited and saved the template itself (not a copy), and that the product is actually linked to that template rather than a different one with a similar name.
