Mobile is currently not supported. I assume it still works on supported platforms?

The sort page is planned on getting updated soon. The current implementation is known to also not work on some touchscreen laptops.

@Lineker: Thanks for your reply. So indeed my mobile phone is the problem, or specifically me trying to edit with mobile phone. No problem, I understand. I haven't tried editing with laptop yet, so I don't know if it will work on my laptop. I will try the laptop, and I will also post the result (positive or negative) on this thread.

@Travis Bell: Also thanks for your reply. I understand and I will wait for that, in the meantime I will try using laptop for this. Whoops, that sounds like a contridaction. My laptop doesn't have touch screen. Like I said above, I'll try the laptop and return to this thread to tell the result.

Thanks for the update Travis!

Hello again,

Problem solved, have tried on laptop and it worked immediately.

So I'm going use that until the sort page will be updated.

And I'll say it again, no problem. I understand.

Thanks.
