Hello Team,
I found this issue while creating a defect/bug in Jira.
If you switch from Visual to Text in the Description section while creating a new Issue, the entire page resets and you lose whatever value you had previously entered in any of the sections.
We are using following details for accessing JIRA;
Operating System: Windows 10
Browser: Edge browser
But on the same os we have verified with IE 11, FF 56 or Chrome browser then Issue does not happen.
That means this issue occurs only with the Edge browser.
Please look in to this & let me know.
Thanks!
