Which hybrid app framework for iOS and Android?

Hi folks, I have an app that I'm trying to develop, but I'm finding difficulty selecting an app development framework. The app basically requires users to create a profile, and store encrypted data on a cloud. I'd like to use AWS.

I've tried Phonegap - but it doesn't seem supported by their dev team. I can't even launch the desktop app on Windows 10.

Tried React Native with Amazon Amplify and AWS. There are too many errors and deprecated dependencies in their sample projects (with the tutorials I tried). Only seems to be 1 developer advocate at AWS who is contributing to React Native + Amplify tutorials.

I had a look at Xamarin Forms. The samples on Github were updated between 2 and 5 years ago: https://github.com/awslabs/aws-sdk-net-samples/tree/master/XamarinSamples

I would appreciate any advise or links to sample code repositories (with authentication functions) to get me started, on a framework that is supported. Ideally on AWS.
