Edge 510 Bluetooth Slow Upload Firmware 3.5

I updated my Edge 510 to firmware 3.5 and since then my upload to the Garmin Connect App via bluetooth has been very slow. My phone and app are all updated to most current versions. Anyone else have the same issue?

Is it possible to go back to a older firmware?

    Yep, same issue here. I did the update to fix some other issues I was having and now uploading a ride is very slow and takes several tries before it works. Did you figure this out?

    Upload slowness

    I have updated to the latest OS version 3.50 and experience super slow uploads, that take multiple attempts to get it to complete successfully. Anyone figure out a way of making it go as fast as pervious upload versions?

    Possibly related, I have this going on with the Edge 810 and iOS app all at latest versions. It's ridiculous. Prior to updating firmware (which I had just left at factory until very recently installing the desktop Connect software which updated the firmware without even prompting me!) an upload of a ride would take half a second, now it fails 100% of the time. Rides only upload at full sync which, for no apparent reason, now takes many minutes.

    It has rendered the app completely useless as this sort of time delay makes it more practical to just plug the thing into the computer when I'm in the process of shedding all my gear and such after a ride.
