How to use bitwarden on Apple Iphone Ios Apps

Ive been using bitwarden (BW) on android fine and now switched to Iphone and am having a hard time getting started with getting BW to autofill my Apps.

for example. dropbox… the dropbox app tells me that bitwarden has not completed this feature?

and just the most basic question… do i have to do something in each App (e.g. share with BW) or do i just have to configure the IOS setup > autofill settings

Seems to works OK for me. Have you setup BW for Autofill in iOS?
