We just updated the Android servers. Details are in this blog post.
Most users will not notice any difference. Let us know if you have any questions!
Wow! That was an adventure. It turns out a lot of jobs have trouble with the updates.
For now, we have reverted to cordova-android 9.0.0. We still encourage people to test their apps with the new release. To do so, add this line to your config.xml:
<engine name="android" spec="10.1.1" />
Stay tuned!
