I found “two-step authentication” must be enabled to log in my add-on development account, but it disabled again and again after I enable it. So it asks me to enable it again and again, and I can never log in into addon manage page now.
I also tried to add 2fa on my account setting page, a “remove” button showed, so that’s correct. But if I refresh this page, it shows “add” button again! How can I enable it?
BTW, I use keepassxc totp for the qrcode scan, will that be a problem?
