@leocg The backup stored corrupted account which I cannot remove. When I fixed my initial issue, only then I realised there is no way back fo Opera account.

Today I faced with an issue with Microsoft Authenticator for my working account. The only action helped me is reinstall the App. But after that I cannot restore Opera account MFA.
I did not remember restore codes (usualy I store such data).
My PC browser is still syncing, but I lost an access to my account from the PC.
But, I still have access from my phone. Which actually do not allow me to do anything...

Is there any way to restore the account? Or it's lost forever?

UPD: Hopefully, I found these reseve codes.

1. Не сохраняется настройка с переводом при нажатии Ctrl. Из-за чего возникают ложные срабатывания.
2. Нет возможности вынести иконку расширения на панель браузера. В старой версии так удобно было переходить на сайт.

After lates update I saw that you replaced a useful "Resently closed" button by "Search". It was one of my favourite function in Opera, because it simple to use in two clicks. But now I should open the lateral panel (1), chose what I closed (2), and close the panel (3). So +1 useless step. And it is so unconfornable to use!

Please, turn my favourite button back (or make it configurable for turning in).
