you don't happen to have a worker or anything overriding that, right? If you go to your account level in Cloudflare, there's a "Trace" option, "Begin Trace" and input https://betaapp.slidesome.comhttps://betaapp.slidesome.com, worth a sanity test, useful utility to learn too
oh sounds like asset preservation cache, was thinking it wouldn't be because index.html should still exist in both versions, but I guess in the new one it doesn't/it's all through functions?
if there's nothing in code on your end, it's the only thing I can think of that would return an Age header, and the cache lives on your pages.dev but with the full url of your custom domain (as weird as that is), so it's both not clearable by you and specific to that url (and of course the cache api is point of presence specific)
yea except I imagine when you "replaced" it, you didn't actually replace the index.html but instead got rid of it all together with ssr now handling it
or wait out the expiration/eviction of the cached asset (stop visiting the site, it'll be evicted after based on access frequency), or use a different subdomain
