Steps to reproduce the problem:
1. Go to Google Play Store under Settings
2. Manage Android Preferences
3. Accessibility

What is the expected behavior?
The ability to change display scaling (also known as DPI scaling) has been a standard feature of Android since Android 7.0 Nougat, and yet this feature is not available for Android apps on Chrome OS. At the moment, The default Android app scaling is too small on Chrome OS. Separate scaling for Android apps is a crucial accessibility feature that strongly affects the user experience. 

Without separate DPI scaling for Android apps, the Android integration within Chrome OS is nowhere near as good as it should be. There is no unified user interface on Chrome OS anymore, since the display size of Android apps is different from the display size of the rest of the operating system. Furthermore, Chrome OS users expect Android apps to work the same as they do on they smartphones. If smartphones with Android 7.0 and up can change the display scaling of the UI, why can't Chrome OS devices with Android 7.0+ do the same? 

We simply need larger text and larger touch targets in order to use Android apps on Chrome OS properly. Keep in mind the ability to change the scaling of Android apps is not just an issue of UI consistency, but an accessibility issue: People with vision problems or other physical disabilities need a Display Size setting for Android apps. Without this feature, Chrome OS is making the user experience much more difficult for some of the world's most vulnerable people. 

What went wrong?
The ability to set the DPI scaling of Android apps separate from the DPI scaling of the rest of Chrome OS was originally introduced in Chrome OS version 65, but has since been removed by a developer for no reason in Chrome OS 67. No equivalent to Android app scaling has been introduced since, and the developer who removed this feature has refused to acknowledge this issue despite countless users reporting this as a problem. 

I would like to point out that the decision to remove the accessibility feature of Android to set display and font size may actually be a violation of the law: https://www.section508.gov/manage/laws-and-policies

Did this work before? Yes Chrome OS 65
