2 FAS Auth - Two Factor Auth. properly set-up, but auto-pasting of codes defect in Vivaldi

I am using the Vivaldi-Browser (Chrome-based). The app was successfully connected to the 2FAS web browser extension, but everytime I am confirming the transmission of a code from the app towards my pc browser, an error occurs "Something went wrong".
