Anybody else notice that on the Garmin Connect website, the "look through" Activity List feature that shows the Training Load and Primary Benefit for each individual activity stopped displaying activities on Wednesday, December 18th and no more activities are showing up since then? I've logged three activities yesterday and today and they appear in Garmin Connect on the website, but, NOT on that one Activity List screen. Just me, or, is everyone experiencing that as well?
Mine has been missing i all december. 
Not sure what you're looking at. Would you post a screenshot please?
As for training load mine appears to be ok.
Do you mean this screen? If so, all seems normal to me. I edited the displayed metrics in the list to include the data you mentioned, but the activities are all present and correct.
No, this screen. You get to it by going to the Training Status breakdown first and then there's an Activity List link underneath the Exercise Load chart that allows you to see this list of activities and their TL along with Primary Benefit. Mine hasn't updated since Dec 18 even though I've done a bunch of activities since then.
Correction - they are there, but they are listed in order of training load, not date. Nothing broken after all, for me.
Events prior to 16th December were tracked with my 5X+, so training load data is not shown for those activities for some stupid reason. The 5X+ does track training load, so I don't know why there is no data there. But the 6X data looks all present and, presumably, correct.
