Checklist:

• Login
• Open F12 Development tools
• Check for /_matrix/media requests, there should only be /_matrix/media/v3/config and /_matrix/media/v3/preview_url requests (As matrix-js-sdk seems not migrated that.)

Excuse me, but why are your git commits "unverified"? Did you forget to upload your GPG key?

I didn't forget to upload my GnuPG key, unfortunately my GnuPG key on smartcard setup seems to have problems and GnuPG can't sign a proper signature that can be verified by itself.

I'll have it fixed, thank you for notify me this.

@ShadowRZ can you please add sw.js file redirect in /netlify.toml so it can be tested on https://1930--pr-cinny.netlify.app/
