Addressables - UnityWebRequest ConnectionError : Malformed URL (IOS) - Unity 2022.1.0f1

Hi,

I was asking about a similar topic here:

In the meantime I updated to Addressables 1.21.1. Also I have a Product Name without spaces.
But I keep having the problem because the WebRequestOveride function is not even called and the addresses from the catalog are pointing to a non existent URI in my case. I need to read local files where the folder structure is determined at runtime. That is why I am dependent on the override function. On Android it works just fine. Any ideas?
Thanks
