I am not sure what is going on, but i cant delete words, back space, all the letters are only 1/2 showing when i write a post. It wont let me delte or edit the last three posts that i just posted.
I had the same problem but I kept typing carefully and when I was done it did show up that I could review it before posting. Just letting you know it isn't just you.
After I hit enter it shows it and I can edit if needed.
