My ANT+ sees my device but when transferring data it starts but then fails saying can't sync with servers, I have been in contact with Garmin, they have sent me loads of ideas to fix it but nothing works, deleting the software, turning off scanners, using fixit s on.
The last time I download Garmin express 4.1.12.0 I noticed in the program it say's it's 3.2. maybe this has something to do with it? (last month I downloaded the new windows 10)
