Android App: Revisit a zone. Check the Sponsor menu. "Takeovers since startup". Sometimes the takeover is not recorded as a revisit. At least the counter Revisits is not increased. At such an occasion the voice sound "Zone taken" is not played. However the text box "Zone revisited ..." is always displayed. The revisit seem to be recored by the server though. Always when the voice sound "Zone taken" is played, also the counter Revisits is increased by one in the Sponsor menu.

July 10, 2016: I did 24 revisits (counted manually). Only 21 of those were displayed in the Sponsor menu. July 12, 2016: I did 28 revisits (counted manually). Only 18 of those were displayed in the Sponsor menu. However, I received the "Revisitor" medal after 50 revisits (counted manually). So all revisits must have been recorded by the server. The issue is non-critical, but a bit annoying. I was nervous about not receiving the medal, but since I got it the important part is working ;-) BR / Perrac
