Google play console no longer tests app on most devices - google-play-console

Question

Since updating my android studio on the 15th of January 2019 the google play console is no longer testing my app on any devices other than the P8 Lite Huawei. All the other devices state "This device could not be tested at this time, please upload a new APK".
I cannot find any information anywhere as to why this is occurring. Is it due to Google no longer supporting tests on those devices? Or is it a change made to my code with the update?
I have included my gradle code in case it's due to an SDK conflict or something but frankly, I'm stumped.
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.frozencodegame.evolution"
minSdkVersion 21
targetSdkVersion 28
versionCode 27
versionName "0.0027"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
aaptOptions {
cruncherEnabled = false
}
Apologies, I have now included my manifest too:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.frozencodegame.evolution">

</application>

You can see what devices your app in compatible with by using the Play Console (help docs)
Sign in to your Play Console.
Select an app.
On the left menu, click Release management > Device catalogue.
If you haven't already, review and accept the Terms of Service.
Select the All, Supported or Excluded tabs.
If you want to download a list of devices as a CSV file, near the right side of the page, click Download device list.
Other devices are not being stopped by Google in general. If you need more help from stackoverflow users, then the problem is usually caused by the app manifest. You may need to add your AndroidManifest.xml to your question.
