Everytime you update StreamFab Peacock thinks you are using a new device. If you only have 1 or 2 devices listed you probably won't see the kitty and it will not offer to remove the old devices.

Never seen this happen from upgrading, but then again, every time I visit Peacock it requires me to log in and to select the profile.
I always thought the kitty was from the built in browser being out of date.
