In order to enable the synchronization, the synchronizer will automatically truncate text that exceeds the Jira limit. We'll show a message that the content of the field has been truncated and a link to the work item where the user can see the full text. See the example examples below.
Fields containing truncated message won't be synchronized back to Azure
As long as the synchronized text field contains this text, it will not be synchronized back to Azure. We do this to prevent the overwrite of Azure field with the truncated text. If you want to resume the synchronization of such fields please remove the mentioned "You have reached the max character limit, the full text with ..." or "Field has reached Jira’s allowed max character limit of 32767. Exceeding content was truncated..." excerpt.
