Or maybe I am. The behavior you’re describing is indeed correct: clicking on the timestamp is also documented among the tips and tricks.
What I’ve been trying to say, is that I get the feeling the ‘jump to end’ problem is mostly seen (and reported) because, after the migration, the forum would, in many occasions, send a user not to their last unread post in nya given thread, but at the beginning or in the middle.
I had threads where it would send me to some post dating back to 2015. This is most likely because vB and Discourse handle these things differently and the fidelity of the conversion isn’t 100%.
If you’ve followed my posts whenever matters of forum switches came up, the issue with fidelity is one I’ve warned people time and again - in a previous life, I ran my own forum and experimented with these things myself.
Based on that experience, I can definitely agree with everybody saying that, by the standards of forum migrations, this has hardly been a train-wreck.
