Callbacks are not working in Unity/iOS

Hello!

We're using Unity 2021.1.22f1. There are a valid product and paywall info in the web app.
However if I build a Unity project from the git repository with my public SDK key, I can't make it work.
For example, getting paywalls process or identify process never return a callback to Unity.

I've enabled a verbose logging:

AdaptyiOS getPaywalls()
AdaptySDK.AdaptyiOS:getPaywalls(String)

2021-10-13 23:51:14.922088+0300 AdaptyUnityProject[23769:2980029] AdaptyiOSWrapper getPaywalls()
2021-10-13 23:51:14.922+0300 [Adapty v1.0(1)] - INFO.
Calling now: getPaywalls(_:)
2021-10-13 23:51:22.463+0300 [Adapty v1.0(1)] - INFO.
