Logging into Garmin Connect this morning, my activities are only showing the map and high level details like distance, time, and pace. The details below that are not showing, like the laps and splits. I've tried in both Chrome and Firefox with the same results.
Same here. I opened a separate thread at the same time as you.
I found a workaround, at least for me. Change the activity type (i.e. from "Running" to "Trail Running"), and all data will load. You can then change it back to the correct activity type and all data should load correctly.
