A long time ago I implemented iOS IAP succesfully in Godot 3.2.3.
Now in Godot 3.3.2 I get that the engine does not have the singleton.
There is something I do not quite remember and I cannot find in the documentation:
Is it required to create a custom .a file by comining a template with your own exported .a file?
And if yes, where were the steps documented how to do this.
Or did anything else change between 3.2.3 and 3.3.2?
