Steps to reproduce:
Is this an issue with PowerApps or we can do something to make it work on our side?
Have you solved your problem?
The "Improved app rendering (final validation)" functionality is used to make app rendering more efficient. If you turn off/disable this option, your app would be rendered in classic mode.

I want my app to render more efficiently. So, this is not really a solution, it's just a workaround. I hope Microsoft will fix this problem with new rendering, and that'll be a real solution.
Hey Kris @v-xida-msft, I'm experiencing the same issue, and found this threqad while searching before opening a new one. For others having this issue, the other workaround I have found is to enable the new? "Show Navigation" feature/setting on the Gallery's Properties. Running the latest build of the client, iOS11.4.1 (latest) and tested with a brand new app published just prior to writing this. This can be easily duplicated by simply adding a new gallery to an app and pointing it to a SharePoint list. Definitely a bug. Please have someone test and escalate to product team for remediation. Thanks for your time and consideration.
