The crash statistic may be an invalid indicator. Problems in your app will no longer manifest themselves as crashes in your native code because the only native code running is iOS's.
Hi, author here. Yeah that's a great point. With Capacitor when the browser crashes you just get this white screen and it wouldn't get picked up as an exception by iOS and reported on the App Store. I ended up having to add in custom JS crash reporting to catch browser exceptions, but I'm not 100% happy with it.
