Has something changed? Guests cannot edit comments anymore

Hello,

Wp-discuz 5.3.6 here (not 7, last test I ran, it was a white page, but I have yet to test with the latest 7.x.x update).

I’m getting complaints from visitors that they cannot edit anymore their comments, and I tested as a guest, it’s true.

And yet, “Edit Button – Allow comment editing for” is on 24 hours.

Would there be an option I’m missing, to allow guests to still update their comments?

Thanks if you can tell me!
