I finally got this working. It’s not that simple because Suunto App is not on the list to open GPX file if you using dropbox, drive etc app in your phone. This depends what Android model you have, probably. But when I opened GPX-file from web page (dropbox) I was able to select Suunto App from the list. I think this is huge problem because there definitely should be importing option in the Suunto App itself. Can you please add that in next version. Thank you
