As I noticed in a widget I created, apparently tones do not work on the Fenix 5 plus.
Investigating this further, I used the sample app Attention and installed it, no problem, all tones did work.
Then I made some slight changes to the Attention app (in AttentionView.mc, function onLayout, initiate selectedIndex = 1), made it a widget, installed it as a widget, and now only TONE_ALARM works.
Question: is this by design, or is it a bug, that widgets only sound the TONE_ALARM, and remain silent on all other tones in the Fenix 5 plus? If by design, does it also apply to other devices (definitely not the Fenix 3), is it documented somewhere?
