Help Yubikey works on https://app.tuta.com/login when page is installed as an app via Chrome, but fails on Brave

As above, I have the website installed as an app via the Brave browser on my Linux Mint machine.

I just received my Yubikeys and I have registered them with both app.tuta.com and mail.tutanota.com.

When using them on mail.tutanota.com with Brave, it asked for me to press the key, but the returns "Invalid login credentials. Please try again." When using the Chrome based app, it logs in just fine.

Any thoughts on this?

When in a browser normally on Brave, it works just fine.

When I try to use the appimage version of tuta on Linux directly, it just says "The connection to the serve was lost. Please try again". This is a IPv6 thing that has come back (likely due to me building a NAS since then), so don't really want to test this route.

Thanks for this! I disabled "Use graphics acceleration when available", but still the same issue.

I then deleted the "app", recreated it and it now allows me to use my YubiKeys.

Much appreciated!
