@emil I installed the Home+ 5 app. When I go through bridges and then display accessories, it works fine with the flic buttons. I think there are some bugs in the iOS 15.3 button/switch portions of the home app.
I had this requirement and solved it by linking Zapier (Free account) (5 Zap limit I believe so if you need more perhaps not the right email option) and then using a service called Firetext (UK based) to deliver the text messages.
And yes it works 👍 .
You will need to pay for credits (the first 25 are free) £20 for 500 so depending on what you want this combination, as a way of using a flic button as an alert service, it works well.
However!! Zapier is not instant so if anyone knows of a service that will email instantly I would be interested (I will keep looking).
The reason I mention the delay is for those who are looking for a Panic Button Solution as the above combination can take between 30 seconds and a few (less than 5) minutes to deliver the text, the delay is with the Zapier free account, unfortunately. 😞
But if you need an alert as an email/text this workaround/combination is by far the simplest/cheapest I have found and it works :).
Was thinking of getting a hub but not interested if it does not work. I have the same issue and any other chrome cast function just does not work. I have 2 phones and one works perfectly fine when the other one doesn't so it just seems to be a software issue or it could be not having a certain permission on my phone. But I have allowed everything I can think of and there should be more information on what permissions I need to enable. The fact that this is a problem and nobody has been able to get a fix for months makes me wonder if this will ever get fixed.
