Great app to come, but still needs significant troubleshooting

A great app to come, but still needs significant troubleshooting under iPad Pro & iOS 10.1.1 (or iOS compatibility update?)
Addresses in search field dont show position marker on map, so unable to determine accurate locations in dense cities
Tap & hold doesnt work on iPad Pro, adds a position marker
Doesnt compute shortest route in running mode in town, keeps following one-way streets.
When looping path, deletes original location of landmarks (too bad when sightseeing places of interest)
Doesnt sync between iPad Pro & iPhone 6 under iOS 10.1.1

Will uninstall and ask for refund.
