Brave premium session expires every 3 days

It’s not e-banking or anything critical. Shouldn’t this authentication last much longer? Brave are also using this system with passwordless login so it’s not the fastest login experience because 1) it doesn’t use the brave password manager to automatically fill in my email 2) it doesn’t even let the browser keep a drop-down of emails in the email field so I have to type my full email every time.

Could someone with premium please confirm that this is the case for everyone and not just for me? If it’s just for me then maybe it has to do with the fact that I tried to sign in on more than one browser so I need to fix that somehow.
