@djay @Emil After several attempts to reset the Hub LR again and stuck even not getting it back/discovered by the Flic App, now it's back. And out of the blue the “Configuration needed - need to pair Flic Hub with your home - wants to access Home-Dialog, showed up again.
I have no idea what caused the problem and no idea what really solved it, other than to try and try and try again for two hours. 😕
