Bitwarden Autofill iOS

Hi there,

Recently switched to Brave. I have BitWarden set up on my iPhone with autofill enabled. It shows up as an autofill option when I visit a website in Brave but when I select to autofill from BitWarden the Brave app freezes and does nothing. Autofill from Apple Keychain works. BitWarden autofills in the Safari and Chrome apps. Any help would be much appreciated.

iPhone 6s
iOS 12.4.1
Brave Version 1.12.1 (19.09.20.23)
BitWarden Version: 2.2.4 (58)
