Hey, I tried again and this time it worked (I was able to access the DM).
Some info:
- The post was created 1 hour ago by a regular user (who also joined 1 hour ago)
- I clicked on the tab on the right > Make Personal Message > the page reloaded and the post was made into a DM with me and the user, as expected
So there must be something else behind it - sometimes it works, sometimes it doesn’t.
(If it helps, I have noticed that this might only happen when the user has posted twice in the same thread (i.e. two posts in a row), but I’m not 100% sure).
