Translating over to android
After we rolled out initial experiment to 100% of iOS users, we then shifted our attention to getting the experience translated to Android. Android already had a formatting bar with similar experience but was behind a button to turn on/off with off being the default state. As a result we made the decision the experiment should not only introduce the new formatting experience but also remove this logic to make it little more easier and clear that these options exist to all users.
Also with this translation had to account for few differences between Android & iOS editing experience. Such as Android didn't have any coloring, indent, or alignment capabilities so as a result we decided to not include those with the new formatting bar, instead leave that for a later iteration. Also the insert button needed to direct user to the attachment bottom sheet, an experience slightly different from iOS.
