Please, if you want updates on this, follow the sportablet account un facebook or twitter. I can either spend my time trying to fix the app or answering all the emails :-).
A couple of days ago, the folks at Garmin made some changes to their website, specifically to the file upload part, which is no longer compatible with my app. There is no official support for third-party apps uploading to Garmin Connect, so this may happen at any time. When it does, I have to understand their change and find a way for my apps to do whatever is needed.
Now, guys, please understand that the only reason I have been able to spend all this time (and some money) on these completely unprofitable apps is that I have a real job. However, that means that I'm often busy doing things which cannot be interrupted to fix the apps, or to send an immediate personal answer to everyone who's having troubles uploading. In fact, I've had no time till now to do anything; I don't even know the magnitude of the change or how long it's going to take to fix the apps. I'll have a little time tomorrow.
To all of you who sent me an email about the problem: thanks for the head-up. Sorry, you'll have a wait a little more.
To the few of you who sent me an email every 20 minutes: please keep calm. It's not global termo-nuclear war. You're not having open heart surgery either. You can always export the file to sd card and upload manually to garmin connect if it's that urgent.
To the few of you who thought the best way to deal with this was to hurry to google play and downrate the app: these apps are meant for nice people. Please consider uninstalling.
