@Smurfhunter Hi!
First of all, sorry to hear you are having issue. Just one more thing I wanted to check:
Sometimes the Flics end up in a specific room instead of under the main "Home" section.
If you press the top right menu (circle with 3 dots), the "rooms" should appear in the bottom of this menu, if you have any. Could you check if the Flics are in any of these rooms? If you find them there, you can press & hold them and select "Add to Home view" to have them show up in your Home apps main section.
If this does not work, could you give us some details on your setup:
iOS version
HomePod/Apple TV OS version and model
Sorry for the inconvenience!
