I don't if it is just me or what???

I just notice that when I post or reply to a post on my phone (iphone) my signature doesn't show up in those post. Strange??

 

Test: I’m replying from my phone to see if my signature show up??

 

Nope it didn't show up from my phone.
Now I'm replying from my computer.

 

Another test:
Posting in full view mode instead of mobile view from my phone.

Results:

EDIT: Posting in full view mode from my phone shows my signature in the post.
Posting in "Mobile" view mode DOES NOT show my signature in the post.
