Can’t read QR codes

What kind of Authenticator app can’t clearly visible QR codes? The ones that are trash. You’d expect better from google. I’m switching to a new Authenticator app asap. DO NOT RECOMMEND.

Pain to install

Gave very few options for me to authenticate and in the end gave up as this fell into the too hard category and just deleted the app. Will use a different authentication route
