IPad App and PM's

A really useful feature of PM's is the confirmed receipt function. However, when I send PM's from the IPad, they do not show up on my receipts list.

So is this:

1) User error. If so, what am I doing wrong?
2) Working as intended and a known feature. We'll get to it one day.
3) Software bug. Thanks for doing our QA for us, and a free month of premium access is now yours for your trouble.

I'll answer in the numeric order:

1. Possible - Make sure you have the check mark on before sending.
2. It's been a long known that the site has had issues which it's been working on with iPad users.
3. Thanks for asking but unfortunately there is no free month of PA for it.

Bearing in mind that no one ever called me the sharpest knife in the drawer, where would this check mark be when I'm using the mobile version? I'm not seeing it when I go to send a PM.

When you send a message scroll down and you'll see the option box under miscellaneous options. It's right under where the message pad is.

Those options only come up if you are using the regular full site version. There are no options what so ever on the mobile version. Something for them to work on in the future. I'll just have to remember to flip to the full site any time I want to PM someone.
