I recently downloaded the Charts app someone developed from the Garmin Connect IQ app store. I think I've done everything okay, but I cannot get the new screen to show up on my Edge 520. The only thing the download looks like it did was to cause issues with my Bluetooth connection with my iPhone. I think I got the iPhone issue resolved but I still cannot get the screen to show up on my Edge. Has anyone else downloaded this app on their 520 and was able to get it to work?
