You made a stupid mistake (or maybe the mistake is on me for taking it for granted the buttons would be future proof. Why would anyone make a product that can't be updated? Nobody can be that stupid right?) and wants your first backers to pay again for it. Wonderful.
I don't feel comfortable using something that can't be updated but I don't feel like paying again for the same thing...

@olyckne I got bit by the same thing mentioned here https://community.flic.io/topic/18188/flic-hub-button-unusable-after-ios-16-upgrade

The button is "hidden" in the "default room" which isn't visible in the new home view...
So resetting everything (maybe just readding the button) and creating automations again worked.

I can't even see my buttons in the home app after upgrading. Factory reset of the hub didn't help.

Cool!
Have a hard time getting it to work though.
When it finally found my button it got stuck on "connecting"
