Have I done something?

[IslaMann]

To make all threads appear with most recent posts first? I have to use the flip post button on everything at the moment to read it in order, on both laptop and phone. Have I changed something inadvertently in my settings? Help please, this is annoying me now (short fuse today)

Customise > Other options > Reading direction > Read down like a book.

Or if on app:
More > Settings > Flip direction.

Thank You!
