Up until yesterday, Google My Tracks has been a brilliant app and I was going to give it 5 stars. I installed the update yesterday, and can no longer upload my maps to either Google Maps or Google Docs. When I first tried uploading, I was asked whether the app should have access to Google Maps, Google Docs and Google Spreadsheet. I allowed all three. I have tried using wi-fi and 3G, but get an error every time. I've tried recording a new track, but this also fails to upload. All other apps can access the web OK, so my web connection isn't a problem. I can access Google My Maps on my PC, so my login is still valid. Does anybody else use Google My Tracks? Has anybody else experienced this problem since updating? Is there any way of rolling back to the previous version of an app?
