Activity doesn't contain all of my data

I did a ride yesterday, Cezanne 2, and the garmin ride doesn't include the entire GPS track - it and all the timelines are cut off at about 3 seconds. The ride details show the right aggregated stats - 15.62 miles, 51 minutes, a weighted average power, etc, but it didn't calculate training load or anything because it also thinks the ride lasted less than a minute. I recorded it on an iPad, so I don't know how to find any temporary files that might be associated with the ride. Is there a way to export the ride data again from the Tacx app (on iPad, windows, cloud), or am I just out of luck on that?
