hi garmin,
With the recent 6.5 firmware upgrade on the Fenix 3, there is a new feature called "performance condition" which replaced the previous recovery check feature.
This new feature, when it splashes up to the screen during an ongoing app session (app and not datafields), all inputs to the running app are lost and the existing running app will exit (and current activity will not get saved)
This "bug" seems to be similar to the one previously with autolap coming up at 8.05km and taking over the entire device/app and then crashin the app.
I have tested and determined that it is affecting my custom apps (Generic Recorder, My Custom RunFields) as well as the DWMap application.
This has made these apps to cease to function properly.
Please take a look and revert accordingly.
