I have the Pocket bookmarklet in my Brave toolbar. When I visit a page that I want to save in Pocket, I click on the bookmarklet. I get a message asking me to login to Pocket, with a button to login. I click on the button and am taken to a new tab showing Pocket itself and the fact I’m logged in. I return to the original tab where I’d like to try again. But I’m still facing the “please login” message. I refresh the page and the “please login” message disappears. Again I try the Pocket bookmarklet on the page I’d like to save. But again I’m asked to login to Pocket. It’s an infinite loop and I’m already logged in to Pocket.
I also have the Pocket bookmarklet in Chrome, where it works perfectly.
