I use PrivateEmail.com for my business email. It is no longer working in the Brave Browser. I can log in, but most of my saved email is gone including folders. It will occasionally display some of the folders, but they are empty. I contacted the host, Namecheap.com, and the issue appears to be the browser. It works in Edge browser and Namecheap had no issues with it on their end. So, they said I should contact browser support. Don’t know if it is affecting anything else.
Don’t know how you can reproduce the error without a privateemail account.
I expect it to work like it always has.

I suspect it has something to do with Chromium 100.
