Flipping threads.

[WithaPickleOnTop]

I have a new android tablet.
For some reason in settings on Mumsnet it won't let me flip the direction of my threads. The option is greyed out.
So I have to flip each thread individually. Grrrr.
No such problems on my iphone.
Help.

No MN experts?

try site stuff if no joy here

Thanks south.
Will try and find it.
