Hi @tatiang and @jared - We haven’t met yet, I’m Chris from Thunkable 
First off, thanks for your candid feedback and for being such valuable members of our community for so long. We greatly appreciate all of your contributions and the support you lend fellow community members here so regularly.
We hear your frustrations, and want to do everything we can to earn your trust and loyalty. Below I will respond to your specific points @tatiang.
iOS Downloads
We are exploring what it would take for users to be able to download their projects via Thunkable using their own Apple Developer Certificate, while ensuring compliance with Apple’s policies.
We’d love any additional feedback here for what users are looking to accomplish with iOS downloads, so we can best meet this need.
In the meantime, TestFlight is the best method for testing apps on iOS. It’s what we use here internally at Thunkable to test our releases. This allows you to publish a version of your app to TestFlight and then send a link to anyone who could then install the app on their phone as they would any other published app. Publishing to TestFlight takes about 40 minutes and once that is done anyone can download and test instantly.
Thunkable Live
We welcome all feedback about our Thunkable Live app here in the Community. The size of the bottom bar on Thunkable Live is due to the Apple Developer License Agreement, which requires us to dedicate less than 100% of the screen towards executable code. Your feedback is well taken though, and we’ll look into options to improve the user experience.
GitHub Bug Reports and Feature Requests
While we do monitor GitHub, you’re 100% right that we need to be more responsive and communicative there and here in the community. In an effort to centralize feedback more, we’re considering moving away from using GitHub for Bug Reporting and Feature Requests (more information will be forthcoming soon). Users can always reach out here in the Community, or via our chat support (if you’re on a PRO plan or higher).
Thanks again for your feedback, please do keep it coming.
PS - I’m still fairly new at Thunkable, and would love to chat sometime if you’re ever up for it, to learn more about how you’re using Thunkable, and what would make your experience here in the community and in the product better (in addition to what you’ve already shared).
