Saving new credentials with Autofill feature in Microsoft Authenticator doesn't work

Question

I downloaded Microsoft Authenticator to my Samsung S21. I imported autofill from Google password and it looked good. At first new credentials was added to Authenticator but now no new credentials are saved. The app works when logging into apps that already have their credenttials saved in the app. I have tried re-install the app but it doesn't help. Why did it stop working? Is there some kind of reset to do? The second time I installed the app all the credentials were there without me having to import them from Google password. Empty cache?
