Android released app colors changed across multiple devices, without any update or release

I have different android and iOS apps on their respective app stores made with Ionic + Angular + Capacitor, and all of a sudden two of our android apps which were previously functioning fine are showing changes in colors across multiple devices without any update or release.

App 1
Version 2.1 - Release on Google Play store
Background is dark, when I haven’t provided any dark mode

Ionic CLI : 6.17.1 (C:\nvm\v14.17.3\node_modules@ionic\cli)
Ionic Framework : @ionic/angular 6.0.0-beta.5
@angular-devkit/build-angular : 12.1.4
@angular-devkit/schematics : 12.2.4
@angular/cli : 12.1.4
@ionic/angular-toolkit : 4.0.0
@capacitor/android : 3.2.4
@capacitor/core : 3.2.1
@capacitor/ios : 3.2.4

App 2
Version 3.1 - Development
Custom Secondary color - a shade of orange is now blue
All Texts have turned white

Ionic CLI : 6.17.1 (C:\nvm\v14.17.3\node_modules@ionic\cli)
Ionic Framework : @ionic/angular 6.0.0-rc.2
@angular-devkit/build-angular : 12.2.11
@angular-devkit/schematics : 12.2.11
@angular/cli : 12.2.11
@ionic/angular-toolkit : 4.0.0

Capacitor CLI : 3.3.1
@capacitor/android : 3.3.1
@capacitor/core : 3.3.1
@capacitor/ios : 3.3.1

Have a look here. There is probably a problem with the latest webview. There is no solution yet, only a workaround.
