One of my most-used apps

I have used MM on a daily basis since the days of the iPhone 4. I love the fact that map data is stored in memory regardless of data signal, but I loathe it when upgrading to a new or replacement phone - no OS 25K/50K map data is transferred and it all has to be saved again by laboriously previewing all the areas you are likely to visit. Fortunately, waypoint data *is* saved because this is a huge advantage over other non-GPX mapping systems. I can add notes to waypoints and treat it as a mini GIS. However, I dislike the licensing system intensely because I have lost access to so many useful maps after numerous iPhone and PC upgrades. This is a waste of my money and really should have been sorted out by the developers by now!

Very annoying that backgrounding app causes loss of tracking - otherwise very good

The loss of track recording when backgrounded is a really annoying feature of an otherwise great app. I contacted their support about it years ago and its still not working. You get home from that mega-trek only to find that nothing has been recorded after a certain time. If you use your iPhone for something then having to remember to get MM back to the foreground isn't too bad (still annoying though), but when an incoming text that you don't know about stops the recording it is infuriating.

On my iPhone MM doesn't appear on the Background App Refresh screen to be enabled - I don't know whether this is the problem?

Apart from that it's a really great app!

Still Doesn't Record Tracks Properly - Useless

I got this App when I purchased new maps which I can use on my PC and mobile device. Synchronising routes from PC to mobile is simple and works well. However, recording tracks on the mobile device is useless. The moment the App goes into the background (like when checking email or messages) the tracking stops completely. Once the App is in the foreground again it restarts tracking again. If there is a long gap between the two the App just joins the points with a straight line from where the App went into the background to where it was when it was brought back to the foreground. Absolutely useless! I thought the latest update dated 1 Jun 17 was a fix for this. Well if it was it didn't work!
