I just updated to the latest release, everything is fine, but the fingerprint icon after switching profiles takes a solid 2-3 seconds to show up.
I have three fingers enrolled, but don't think, that that would be the issue. It's quite inconvinient tho.

Hopefully it's just a bug or something

    I am experiencing the exact same issue on Pixel 7 Pro, using Shelter for Work profile.

    Did you find any solution to this?

    I created a couple of secondary profiles besides the empty owner profile on P7. Two of those secondary profiles are using the fingerprint scanner for unlocking. I can confirm above mentioned delays but never investigated further. By chance I just noticed some interesting differences:
    When switching back to the profile without any Google apps it takes 5-10sec until the scanner symbol appears.
    When switching to the other profile containing Google apps (GCam, Photo and the Google dependencies, no other apps) it takes at most 2-3s.
    Maybe the GSF makes the difference? Did anyone observed similar behavior?
    I don't believe the number of apps per profile has some impact to this kind of delay, right?

      ReadOnlyUser I did some further investigation and found out why it tooks ways longer at one profile until the fingerprint scanner appears. It depends on the number of fingerprints! I had four fingers in the slow profile before, the quicker profile just had one. I just dropped all four fingerprints from the slow profile and added them again one by one. Having just one or two is still quite fast. From the third one onwards it's getting slower (and maybe slower with further ones). So I just use two fingers and it works quite fast.
      In addition, I created another profile for testing. Kept all preferences at default but just added one fingerprint. Works quite fast as well. I think my origin assumption that the Google apps may change something in this regards was false. It's just the number of fingerprints.

        I am not using secondary profiles, just Shelter as a Work profile and no matter how many fingerprints I use, the fingeprint prompt still delays when opening apps between profiles (e.g. if I open an app in Owner profile then open any other apps in Owner profile the fingeprint prompt will appear instantly. However, if I try to open an app in Work profile, the fingerprint prompt will be delayed but after that if I open any other profile in Work profile the fingerprint window will appear instantly. Then, if I open any app in Owner profile, the fingerprint prompt will still be delayed and after that all apps in Owner profile will display fingerprint prompt instantly until I switch to Work profile apps, etc).
