My galaxy tab was doing it's usual "tick me off" routine this morning. I'm typing this now from a laptop and the galaxy is on hotspot. Earlier I typed out a long reply this morning on the galaxy. When I hit the submit button, nothing happened

so I hit the submit button again and nothing

so I decided to wait a minute before I frizbied it across the room. After about 2 minutes it said the submit was successful. When I went to the post, sure enough, it duplicated things. In the past I thought if I hurried I could delete the last post quickly if nobody made a reply to the post. Nada. The delete button wasn't there on my last duplicated reply

I tried to erase everything using the edit button, but I had to leave something in the box for things to work, so I left a period(.) Later after I turned on the galaxy hotspot and fired up an old laptop and could view multiple replies at once, I noticed the delete button was available on my first reply but not my duplicate. I did some copy/paste from the first back to the second and then deleted the first. My question------------ is this always how it's been and I'm starting to have "senior moments"
I probably have everyone confused by now,
