I tested in french and romanian (I first thought it’s something wrong with romanian translation), but I think there is a problem with any language that’s not English.
It’s because the variable was changed to replyCount
summary:
description: "There are <b>{{replyCount}}</b> replies."
description_time: "There are <b>{{replyCount}}</b> replies with an estimated read time of <b>{{readingTime}} minutes</b>."
Hmm, indeed. On transifex is still count, but on github is replyCount.
I just updated translations, and can see on Transifex that you updated the relevant key, so it’s fixed for Romanian language now.
I also pushed new keys on Transifex, so updated keys are now available in Transifex for translations.
Got the same case in French on Infinite Flight Community
Spanish have the bug too.
