Hi.
I'm using the JIRA app v108.1.2 on Android 13 on a Samsung S21 Ultra.
Every time I try to add a comment to an issue after a number of seconds the app seems to automatically duplicate some of my text in the comment and then every so often adds line feeds to the bottom of my comment. So 1 comment can have some text at the top and then big white space at the bottom. Only noticed this with the latest version.
