This used to happen to me all the time. And I used to get my messages disallowed, saying I had reached my limilt.
It was so persistent and annoying that I left the community for four months.
Since I returned, I have only had the message issue a few times. And I have not had any posts disappear.
If you continue seeing posts 'disappear' after submission, notify Lara. Perhaps it was just a one-off though.
No, it was my fault. I touched a part of my phone that returned the page to the one before, thus sending my incompetent post to oblivion. I'm very untechnical.
As a non techie. How do the @names get at the beginning of a posted post?
@TXbelle: That is a good question! To include (or tag someone) in a post or reply, you start by pressing the @ then, without any spaces start typing the name of the person you wish to tag. It's likely that a drop box will open for you to choose from one or more names. If the correct name appears, simply tap/select It. If you don't see the name you are looking for, just keep typing until it appears.
I hope you find this helpful. Let me know if further information would be helpful.
