Not sure if this is related to these recent dependency bumps

Manifest merger failed : uses-sdk:minSdkVersion 21 cannot be smaller than version 23 declared in library [com.google.androidbrowserhelper:androidbrowserhelper:2.7.0-alpha02] /Users/maxp/.gradle/caches/8.11.1/transforms/d8c107a39c6aa566b2c022d592784981/transformed/androidbrowserhelper-2.7.0-alpha02/AndroidManifest.xml as the library might be using APIs not available in 21
	Suggestion: use a compatible library with a minSdk of at most 21,
		or increase this project's minSdk version to at least 23,
		or use tools:overrideLibrary="com.google.androidbrowserhelper" to force usage (may lead to runtime failures)
