Well, so far all the tech I've loaded up for my trip has been working. I unfortunately missed the update for my EZFlash Omega DE until today, as that is a VERY convenient firmware update for it since I'm using my Analogue Pocket for GBA games. I had someone amazed at how setup my 3DS was though, haha.
Noticed an annoying bug with the status updates. If you manage to play a video by clicking on the preview then you have no way to pause it because the controls are cut off, tapping again doesn't work and opening the full status update doesn't help because it's actually a separate player.
I don't think it's supposed to actually be possible to hit play on the status preview but I managed to do it on mobile just now.
