We are upgrading Strava's network security systems on November 30th, 2018 to make sure your data continues to be as safe as possible. This change requires that all athletes have a more recent version of Strava to continue using Strava on Android devices. After 11/30/2018, if you are seeing errors such as "Data sync failed," "Network unavailable," or something similar, please make sure you have the following installed:
- Android KitKat 4.4 or later.
- Strava app version 51.0.0 or later. The latest update can be downloaded from the Google Play store.
