Problem:
Just a heads up for anyone doing testing on Android. There has always been an issue specific to Android where you cannot have more than 2 versions of TTA installed at the same time, for example both Beta and Prod. If you try to log into both apps you would get an error message regarding the system account. In the latest version of TTA (4.15) this same limitation exists but the error message has changed. This is due to changes within the Garmin Auth library we have imported. If you see an error message of "Failed resolution of: Lcom/garmin/analytics/AnalyticsHelper" then you have run into this problem.
Solution:
Please uninstall all other versions of TTA and try again. (Note there may be a missing dependency in our build which we will look into but this should not impact functionality).
