@hans-0 same feeling on my side...
But eventually I found it: in the provider menu (where there is IFTTT and so on), there is an IR provider. Select it and configure it there.
Now that I have this, I miss that I cannot activate IR through other means than a flic buton. I wish I could just use the IR provider as the that of an IFTTT recipe, but could not find a way to do that yet.
