iOS app hangs on splash screen

I’ve finally got my phonegap App built (on Voltbuilder/Signer) to a release version for iOS (Android already complete). However the App when tested on multiple iPhones refuses to go past the splash screen. There are also messages that indicate it may not have proper connectivity (login fail messages, which come from server calls). Everything else is exactly the same as the working version (from a few years ago). But I can’t seem to find anything online that might point me in the right direction.

Not sure if it’s firebase related, but hoping someone might notice something in the log below:

The first thing to do is check the iOS remote console for errors. A common problem is CSP issues, introduced by new iOS security requirements.

The error is in that log, see below.

Apr 12 16:13:53 iPad TESTMASTERS.com App(AXRuntime)[12920] : Unknown client: TESTMASTERS.com App

But that log isn’t from the remote console, is it?

I do not have an iPhone for physical testing, so this is from the remote console on BrowserStack.

It’s not the Safari remote console - that’s what should have the messages.
