Using the iOS App

Hi I have the iOS app (3.2.0) installed and running well on an iPhone 7 running iOS 14.4. For security I would like to be able to log out of the app and on opening have to use my fingerprint for id.
At the moment if I close the app, on re-opening I go straight to the Nextcloud menu displaying files, photos etc., even though I have settings lock enabled. Am I missing something? Thanks


Thanks for your help. The fingerprint id is working now.
