After having maprunf installed for a few days, when calling up the app i get the outline of the page and options but no writing in the boxes, trying to go to the start shows a google earth map with the course over the top not an o map. The only way I seem to be able to resolve this is by deleting the app then later reinstalling it. This is getting tedious, it didn't happen immediately i had a good few weeks with it on my phone and did several course but is now happening regularily. I assume it is an issue with the phone settings but can't figure out what. Using an iphone 7. Cant find any other reports of this Any ideas ?
