@ionoy , I finally got a chance to dig deeper into the issue of no being able to render changes and simply rolled back my droid project debug settings to those that worked for LiveXaml before. Changing values for one or more of the settings to the ones listed below resolved the issue. Due to time constraints I did not have a chance to identify which of the mentioned settings specifically caused the issue but hopefully it helps to reproduce the issue on your end and/or others facing similar issue to pinpoint its root cause.
Settings that caused the issue:
Rolling them back to the settings below solved the problem.
What we're seeing, only on iPhones on a particular carrier (EE in the UK) on a pay monthly contract is that the app is locking up immediately it starts. Does LiveXAML try to talk to the LiveXAML server on the UI thread?
Oh - and this is only on an app which has gone up to TestFlight or been published to the App Store.
@ionoy Unfortunately we have narrowed down our problem to LiveXAML. Removing LiveXAML solves the problem. It looks like the only solution to our problem (the app hanging) is to remove the Live XAML NuGet package, as setting the DISABLE_XAMARINFORMSLIVE symbol did not fix the problem.
Note that this is manifesting itself only on iPhones on EE in the UK on a pay monthly contract.
