Unable to auto-fill username after updating from 1password7 to 1password8

Thank god I am not alone. I got myself a new phone today and ended up installing v8 on it. On the older phone, I had v7 so everything was working fine but couldn't figure out why it stopped working now. I was blaming the updated Android version somehow. Took me some time to find out that 1Password is at fault. Please fix this issue.
