Today I had 2 games on PBE.
First was while Normal Blind was still active and emotes were working fine.
Second was when the new Normal Draft debuted and I couldn't use any emotes. They simply didn't show on the emote wheel as if I didn't have them.
I'm guessing nobody could use them in that game since I didn't see anyone.
After the game I went to Collection tab under Emotes, and my emotes were adjusted perfectly there.
I don't know if that bug was for only one game but if anyone else is experiencing it, would be great to upvote or comment on this post so it hopefully gets to Riot.
