I searched LastPass for bug reports re this issue but didn’t see it reported. My version and OS info is below. Here’s the issue:
I have 2 Factor Authentication enabled for LastPass. I can install the LastPass extension in the Brave browser, log in to LastPass with my master password, then I am taken to the 2FA screen. There is a hyperlink that causes LastPass to send a code to my mobile device via SMS. That works fine. But, as soon as you click that hyperlink, the entire dialog box becomes unresponsive, meaning: The SMS hyperlink cannot be clicked again, the textbox for entering the 6 digit SMS code will not accept any user input, and the “Trust this computer for 30 days” checkbox will not permit user input.
