I have two separate 830 MTB Bundles, one is mine which I've had since it came out and the other is my wife's purchased a week or so ago new.
I've followed every bit of instructions I can find and both of them still give me the "Map cannot be unlocked" (or whatever that actual text is) message when attempting to unlock trail forks. They're paired to different phones, and different trail fork accounts. In both cases they can see courses in trail forks on the device so we know that they're actually talking to trail forks they just don't unlock the maps, so we only have the 2019 map and haven't gotten a new one.
We have tried deleting trail forks and re-downloading, re-pairing, and re-connecting with connect, nothing seems to solve this problem. I have also tried with the phone on wi-fi, and not, with the garmin on wi-fi and not. I've got a 2 week thread with Garmin (although they've not said anything since this past Monday) on it, and still no resolution. It seems really weird to me that two devices with nothing in common (separate phones, separate garmin connect accounts, separate trail forks accounts) are doing this unless there's just a fundamental bug here.
If anyone has any thoughts that I might not have already tried please let me know.
thank you
