I still cannot collect any trader tenders from the chest, the animation kicks off, no loot. I also never received the tenders from completing the quest. I also never received tenders from completing trading post quests.
I cannot interact with this brand new system I was very much looking forward to.
I am having the exact same issues.
Same here bought the pet never got it. I keep opening the chest and only getting tenders.
same here.
Same here. It’s pretty frustrating.
They fixed it? News to me and my opening and closing chest of uselessness.
Yeap. Same, if there was a fix, it didn’t work for me either. Last 3 days i’ve tried going to the chest to get my traders tender, animation goes off, no currency. I’ve gotten no traders tender for completing the bar or turning in the quest either.
same issue here for me. completed the traveler’s challenges and cant pick up the mount from chest either
“The time lost chest of nothingness”
Same here 
Same here, still having this issue. Cannot get my tenders despite trying literally everything: relogging, disabling addons, reloading my UI, clearing my cache folder, logging off for an extended period of time, trying with different alts on both factions and in different servers and regions. Nada.
I maxed my bar thinking that maybe unlocking the warden mount would somehow do the trick, and still, nothing. So now I have no tender and no mount. This is honestly very disappointing, transmog and mounts are a thing that I enjoy collecting and so this was a feature that I was greatly looking forward to.
We’ll keep waiting, I guess.
