I’ve checked chat for private messaging and it seems to work normal, but for some reason only today, when clicking on “reply” to e-mails, that feature does not work any more.
I also notice that I cannot reply to posts either.
It’s the first time I have seen this happen. I also tried with different messages and posts, so this has zero to do with the message limit of 500 for messaging, which was discussed for a prior ticket.
