Welcome to the LastPass Community!
In this case I suggest to review this article and make sure the settings for autofill are enabled: Use LastPass for autofill via the LastPass Password Manager app for iOS
Or review the general overview: LastPass for iOS autofill overview. If all settings appeared to be correct and you still experience issues please submit a case in our support portal: Contact us.
Thank you,
