I purchased Adze in May 2017, and have found it quite useful for viewing & editing gpx files. However, since November, 2018, I can see my gpx track, but no background map - just a white background. I tried “street”, “satellite”, “hybrid”, and “terrain”. I’ve zoomed out and zoomed in, to no avail. My track could be in Maine or California or on the moon. I have emailed Kobot Software 2 times in November and once in December, but have received no response.
