While trying to adjust the touch settings to a way that works for me I noticed an anomaly.
The touch setting for some activities does not work. One example is the "Map" activity. This follows the general use setting for touch rather than the Map activity touch setting - so if the general use setting is off but the map touch setting is on (as I have it set), touch doesn't work for the map activity as expected.
After some experimentation I think I've spotted what's going on. For most activities like "Run" or "Walk", the touch setting for Run and walk only come into play once the activity is actually started. While the activity is in the preview stage (while getting GPS lock etc) the touch setting for "General Use" touch setting is used. (this is probably the bug?). For most activities this doesn't matter as you usually press the start button soon after to set the timer running etc. But for some "Activities" like "Map", the start button has no meaning so it's always in the preview phase.
I think the fix should be to make all activities observe the touch setting for the activity while in the activity preview stage (timer not running).
I see this has been reported before in various ways but I don't think anyone made the connection that the touch setting for an activity only works if the timer for that activity is running. e.g.
