Hi,
since I have upgraded to Version 4.3 of the Android App, it is not possible to configure activity options any longer.
I only see a black screen, when I go into Devices --> activity options --> and try to change the settings for walking/running/etc ...
When I use the back button, there is a message "settings were saved". Maybe it is a simple bug, black font on black backgound maybe ?
I am usung a vivomove HR.
Regards,
Willi
