I visit zones, some record me taking them, and others (most) do not.

I arrive at zone, get message that I am taking zone. Yellow bars climb up LHS of screen to the top but no arm raising of icon, and no accrediting of having taken the zone. Red icon often seems to be flashing at top of the yellow (taking) bar. While turfing with my daughter, we noticed that when this is happening, my icon doesn't even show on her phone. Other times we have successfully trufed together, and I have had two local zones registered to me when I have been alone. Only two out of my 6 local turfs have worked for me, and one of them didn't work the first time I visited. (Some of my local zones are also inaccessible)
