https://client.ampache.dev/ is using tinysub at the moment.
https://client.ampache.dev/client is the path for ampache webui access but it gets hijacked from the root app path for tinysub
I can get to the page fine with a ctrl + shift + r to force refresh.
ampache paths the client ned to access from the root path /client /rest /server /admin /daap /upnp /webdav /jellyfin /oidc
I haven't looked at whether other areas are affected
navigateFallback: nullin the Vite PWA config should fix this, it should have been set before, but i forgot :pcommitted in https://tangled.org/devins.page/tinysub/commit/c04ea8af00b80318f83e9247e8c06a31bece0828 and available in release 2.86.7
let me know if you still have problems (you might need to unregister the service worker in devtools and then reload? tho the update button should handle it properly i think...)
