Plugins not installed on iOS

Hi there. I’m hoping there is help out there!

I’ve built my app for iOS and I’ve managed to push the app onto an iPhone. When I begin interacting with the app I’m getting errors telling me that I need to install plugins.

[Warning] Native: InAppBrowser is not installed or you are running on a browser. Falling back to (vendor.js, line 102520).

This is just one example, I have a few plugins and two of them are used on my login screen and both of these are failing in the same way. What am I missing?? Thank you.
