Yesterday, I turned on MN and realised most of the threads had their OPs at the end. That happen overnight and I don't think I flipped them unwittingly. As you can see I said 'most of the threads', because some of them are in the right order . Now I can flip the threads I'm reading on my laptop (8/ 10 which is a PITA) but I can't do it on the MN app. If a thread is really long I end up scrolling forever to get to the OP. Help anyone?
I can see through my magical powers that you've got your thread direction reversed in your Talk preferences. If you go to the Customise page, you can set this back so that oldest posts will appear at the top (the option is called "Reading Direction" about halway down the page).
Hopefully, changing that option should also sort out the problem you're having with the app. Let us know if there's still any issuses though.
