When trying to log into my Amazon account it is saying that it can’t find an account based on my e-mail tied to my account. After trying on my cellphone via the Amazon app and on Google Chrome I found I could log into my Amazon account just fine. This seems to suggest it is an issue with the Brave browser on my desktop.
possibly pointless question, did you use autofill to finish putting in your email address? I ask because I’ve noticed on some sites it seems to add a space at the end, has caused me some failed logins before I saw it. (not amazon though, i use the app)
