HTML Tags in Description Field on Jira
When you sync your user stories from Salesforce to Jira you may see that html tags are added to the Description field in Jira. This issue is related to Jira editor and format of the Description area. Copado__Functional_Specifications__c is a rich text area field while description is a free format text. Per the document linked below, not every format is supported on Jira: https://jira.atlassian.com/secure/WikiRendererHelpAction.jspa?section=all.
If you need HTML to be supported, you can use additional apps from the atlassian marketplace like jEditor.
