I can confirm this error, if I find a solution, I will update it here.
I couldnÂ´t find any hardcoded ip adresses though, are you sure the preview is related to the error?
First off, Thank you for the reply, there is hope and we are not crazy as of yet!
We believe (remember we are noob programmers, which is why we use Construct2) it is preview server related due to our only seeing this IOS issue after enabling that option in preferences (whatever it adds to our build for cordova?) and apple insisting we add both iPV6 and iPV4 addresses to fix the bug...
apple's response from this sudden appearance of this new bug...
We have reformatted our PC with a fresh windows 10 copy and a new Construct2 install (just to make sure it isn't related to settings in some rogue windows file from previous construct install) and the issue continues, suggesting that once the preference is enabled, it does something in the code (from our naive non-programmer perspective) no matter if we disable it afterwards and open the project on a fresh install of both Construct 2 and windows. It worked PERFECTLY BEFORE on IOS without issues.
I will be tackling this again today, and wanted to try side by side in beta Construct 3, but it says we can't upgrade our construct 3 subscription as of yet? so free edition doesn't help us there to test.
The last thing I'll test (a huge annoyance) is to redo the entire app in a new project, fresh install of Construct2 and Windows, without ever enabling that option to see if the error never pops up (due to never enabling preview server in preferences).
I will also see what we get with your suggestion but am brand new to this WKWebView thing... and trying to make sense (as a noob programmer) of these threads to see if they are related to what we are seeing:

All noob explanations welcome. Thanks in advance. Will return and report after trying with disabled WKWebView on cordova export
