On my Pixel 6 for my venu 3, the datasite configuration in the German app does not work. The app does not show the "two" options on top, which are present in the venu 3, leading to a wrong mapping of the buttons, also making it impossible to choose the last to options in the app. A specific datafield not chooseable from the app is current time.
Bug only tested for cycling activity, might also be present for others. Also not tested whether german specific bug.
Current workaround is to set the datasite from the watch.
The issue should be with the app, because the two ebike options are missing only in the app, the venu 3 shows them.
