Italics and bold not working on app

[LadyBird1973]

Just that really. Am on iPhone and using the app. When I try to use the italics or bold button is may or may not work or will italicise or bold some of the letters in the word but not all.
Is that a phone issue or an app one?
Thanks

Hi OP

Can we ask you to check you're using the latest version of the app? Please let us know what version it is!

I think it's 4.4.28. The app isn't saying it needs an update

I've deleted and reinstalled the app. Seems okay so far. Will update if it's still a problem. Thanks

Thanks, OP! Fingers crossed.
