Probably fixed by https://github.com/tangrams/bubble-wrap/commit/1746d430529a1f85393d3f2c56b5286e06422f90
We should update the versions of bubble-wrap in the Android SDK and Eraser Map
Yes, fixed by https://github.com/tangrams/bubble-wrap/commit/1746d430529a1f85393d3f2c56b5286e06422f90.
I've released v2.0.1, please update Eraser Map to point at this new release.
Is there a similar issue in Cinnabar or Refill? If so we can update those as well.
Oh actually it looks like this fix is already in the submodule commit referenced by the Android SDK (according to this history). Since Eraser Map uses styles from the Android SDK now, the next release will have this fix.
Once we wrap up the current round of SDK changes we'll push a new version of the app to the store.
