Firebase A/B Test with Remote Config doesn't work with specific version on iOS

I created A/B Test with Remote Config 2 days ago and add specific version with Regular expression 1\.4\.1[3-9]. But firebase dashboards shows that 0 users.

Remote Config & Remote Config Key, Regular Expression works perfectly

I'm using

Fireabse 4.5.0

FirebaseRemoteConfig (2.1.0)

The problem is that, after two days, the Firebase Console keeps saying that 0 users have

Is there something I'm missing?
