Click Delay on IOS

Hello, I’ve followed the “Build your first App” guide (React Apps | Build Your First Ionic Framework React Application) and I am able to run the app on my iPhone. However, I’ve noticed that there is a slight delay (or debounce effect) when clicking on a button in the bottom navigation of the app. One can observe this delay when quickly switching between tabs: In native apps all button clicks result in tab switches (see e.g. WhatsApp) whereas in the Ionic app clicks seem to be debounced.
I’m trying to get a feeling how responsive Ionic is but this debounce/delay effect makes me a bit worried, especially because the “Build your first App” is so basic. Is there a a way to overcome this debouncing problem?
