Why is Brave indicating that this site is Not Secure when all other browsers are OK with it?
Issue isn’t replicating for me. Might just be you have an extension causing issues or need to clear cookies.
Btw, it also helps if you include things like which version of Brave you’re using, which OS, etc.
This is running on Win 11;
[Version 1.48.158 Chromium: 110.0.5481.77 (Official Build) (64-bit)]
This is not isolated to a single device. It presents in 3 different devices with the same version of Brave installations, Win 10 & 11. It is peculiar.
