Thanks for the reply.
I tried uninstalling & reinstalling and have tried connecting via WiFi both at home & at work, as well, as over cell data, and I am still seeing the issue on my Galaxy S3 (you thought your S4 was old!), running Android 4.4.2. Also, I tried uninstalling, and then removing (I backed them up first) all the folders on my device related to Bike Tracker that I could find (KML, GPX, SUM, TXC, RWG, Bike Tracker), and then reinstalling, with no luck either.
However, I installed Bike Tracker on my (much newer) Samsung tablet, and it worked no problem (I can see my RWG routes).
So, I'm not sure if my S3 is just getting too far out of date? As I mentioned, it was working for me as recently as April 24th (last time I loaded a RWG route). I have only used the App a couple of times, but was looking forward to using it this summer for the turn-by-turn directions with RWG routes.
Do you have any other suggestions? (are there any log files to check, or logging I can enable?).
Thanks and regards,
Rob
