I made an emote (peepoBike), uploaded it and enabled sharing.
GiantWaffle added it to his channel but it doesn’t show in browsers (to some? including me).
Tc chat client does show it for me as you can see in the screenshot below
Things I tried:
clear cache, use different browsers chrome/firefox and Tc chat.
peepoBike works fine in other channels (Unknown_, Uzknown, Mangosteeeen)
on Firefox, Chrome and Tc chat.
I don’t know how many can see the emote or what browser/chat client they use so it’s a bit difficult to figure out what the exact issue is.
My guess would be: an issue with the browser plug-in / 50 emote limit.
Because it works in other channels but those other channels aren’t using more than 5 emotes.
Then again, I can only judge on my own experience, possibly it works fine for others in their browser.
