TL;DR
The Audible app on Android is using unexpectedly large amounts of mobile data for some users.
This behavior is apparently being caused by a bug in version 26.19.13 of the app.
Audible is aware of the issue, but we don’t have a timeline for any potential fix.
The Audible app is using an inordinate amount of data on Android. User reports are circulating that the audiobook service is eating up gigabytes of mobile data, even when configured to only stream or download content over Wi-Fi.
PiunikaWeb has rounded up several of these reports. Mobile data usage varies, with users reporting up to 17 gigabytes of unexpected data consumption over a period of days. Audible says the issue is being caused by a bug.
