No it doesn't work for anyone in the EU for any type of pwa
So your statement isn’t accurate
I’m in the EU on the latest version of iOS.
People have been saying it's working for them in the EU: the Apple's detection is complex and seem to take into account different parameters, like the ios region, but also the origin country of the sim card used.
But note this behavior only occurs if you are in the EU and you are using 17.4 beta 1 or beta 2
