I'm another with the same problem again. This isn't the first time I have had the problem. The first time a long time ago there was a workaround someone made that fixed it. This addon does not seem to work this time. This problem was fixed by Riot before so they addon was not required. It is not adblocker as I have tried firefox, turning off adblocker, and incognito mode on chrome. Also tried Microsoft Edge and Internet explorer. It does not work after clearing cache and restarting browser either. There may be a few other things I have not tried yet but, I think that would be sufficient enough for now.
This was a problem before that some people were having, but not everyone. It's one of the stranger issues it seems. Is it possible for something on a PC to be causing the issue rather than the browser or addon? That sounds kind of strange to me, but nothing would surprise me. lol
UPDATE:
This is only a problem with using NA English for my language. When I switch to EU English it works fine. Examples of what I see using the final Flash Wolves/SKT game match history in S6 worlds:
