Support discontinued for Pokemon Go for Android 6

Pokémon GO has ended support for devices running Android 6, “Marshmallow”, starting with version 241. We encourage Trainers to update their operating system to continue playing without any interruptions.
Am I affected by this change?
Only devices with Android 6 installed are affected by this change. Apple users and Android users on Android 7, “Nougat” or higher are not affected and do not need to take any action.
If you are unsure of the operating system version installed on your Android device, you can find this information in the device settings. Go to Settings > General > About.
What do I have to do?
Why this change?
A large majority of Android users have migrated to Android 7 and above. As players migrate from older versions of the operating system to newer ones, we periodically update our supported device requirements to focus on the devices our player base is using.
