Draft post disappears or shows old draft text

I'm struggling to type posts as it keeps disappearing as I type or shows an older draft post for another thread. I have to tap the text box then type something to get it back. Then j have to type quickly and delete typed letters in the wrong place due to this issue.
Can anyone help?

The only change recently is that randomly a fresh line of text is started after I've done a 'nudge' to another member's name, or edited a piece of text to change the font into italics.

Sometimes the 'post' button doesn't work right away and saves a draft, so you have to check, otherwise you think you've posted and realise later that you haven't.
