The Devil in the Details
The last six or seven times I've tried to send a PM, it has gotten 'eaten'. Everything gets messed up, and my message doesn't show.
Please find out if this is happening to more than just me, and of so, fix it.
Actually, my girlfriend has tried using the app to send PMs to me- and they are
often eaten, too. So no, it isn't just you, the app seems to eat Private Messages at random.. or, at least, most of the time.
.. it also seems to make thread titles disappear when someone using the app views the thread.
