import GPX folder doest work anymore

I have been using navigator for many years but since few time I meet a bug when trying to open a Gpx folder on my smartphone.

My smartphone has android 6.0.1 version and the version of navigator is 7.2.60 armeabi-v7a .

Previously I usede to "clic" on the Gpx folder, at this time it opened "navigator" and once i made the choice between TomTom or openmap, a window was opened asking if I want to import the points of the Gpx folder selected.

Now after the clic on the Gpx folder, then navigator is opened, but after the choice of map is made, nothing happen, the window asking if you want to import the points doesn't appear!

Does anybidy met this problem or have an idea the reason navigator behave this way ?

Thanks a lot
