[SOLVED] GIFs not animating in the Android version of my React Native app

I am struggling to get my GIFs to animate on the Android version of my RN application. The iOS version is animating the looping GIFs as expected but I only see a stuck "single frame" image from the GIF on the Android device.

According to the debugging and RN-documentation it's required to add a few lines of implementation to the dependencies within the /android/app/build.gradle, but even after cleaning the gradle (running ./gradlew clean in the /android folder) and deleting the cache of the RN app (running react-native start --reset-cache in the project root folder), I do not see any difference in my application.

I have googled and tried a lot. Based on my debugging adventure, I have tried and double-checked these suggestions, that seems to work for others but it doesn't seem to work for me...

I have tried several versions of the fresco-libraries that seems to be required and I have also tried placing the lines in both the bottom as well as the top of the dependencies.
Some answers also suggest to add one or more lines of code to the android/app/proguard-rules.pro but this doesn't change anything either.
I use GIFs in different ways of my application but it always has width and height included to the style property on the <Image />.
I have tried with GIF-uris from different CDNs and domains.
Reinstalled the app on my test devices.
Closed and reopened my code editors.

I'm using the following versions:

Java: 11.0.12
React Native: 0.65
Android SDK: 30.0.2
npm: 6.14.4

This is my full /android/app/build.gradle:

Let me know if I've missed something obvious. I am definitely more experienced in iOS-development, so it is very possible that I missed something :-)
