The mobile version is a pure nightmare - without the choice to reach the full site, I have no idea how it is. Not talking about colors or, technically and use.
It literally jumps, and keeps jumping, like you can't even click.
While writing a message, you can't reach lower lines if clicking to edit (without editing, while wrinting), when the post gets longer, although not this long, just trespassing the box, then you to delete that longer part, entirely.
On mobile, you can only post one pic by one.
My suggestion would be to make it at least possible to access a full site version. I searched and saw that nowhere. Or make "endless"message post.
Also, when the message is long, capchas are asked. I have an anti virus and no S... on my phone. It's incredibly difficult to post whatever then.
