While there have been some changes recently to use Timber for logging, there are still places that use Log.d, Log.e, etc. for logging and these logs show up in release builds of apps including LD. This is true in particular of the HttpFeatureFlagFetcher class (logged as LDFeatureFlagFetcher). Ideally all remaining logging in the app would be configurable (by, for example, switching to use Timber or Logger).
