I think it's dubious if any court is going to care about static/dynamic linking technical discussions, particularly since we're talking about an Android app with Java code, among other things. The GPL license itself doesn't bother with such technical minutiae either. But it does concern itself with distributing GPL code and unrelated code as a "whole"; and undeniably the Wix Android app comes with the Wordpress GPL code. So I don't think this is the particular case that you want to test the whole dynamic linking discussion on.
