This post is a heads up to anyone using the Dropbox sync feature; outdoor rides are incorrectly marked as indoor rides. I reported this bug, which TrainerRoad support confirmed, on 18 Feb. It is late April now and the fix has not yet been made, although it would appear this would be a relatively minor one?
So if you are relying on a archive of your files in Dropbox and care whether your rides are correctly labelled indoor or outdoor, I suggest you add a “me too” or something to this thread and hopefully TR will elevate getting this minor issue fixed ASAP.
