No issues
Has worked with no issues on my iPhone 8 and iPhone 12.
QR code reader does not like low refresh rates
The QR code reader didn’t like that my laptop screen had a low refresh rate. I had to connect my laptop to a decent monitor just to scan the QR code.
Poor
Only button on the main screen doesn’t work. Had to click the camera logo in the corner. Should allow for other authenticator apps to be used.
Easy to use
Very user friendly and simple to work! No problems here :)
