Known Limitations
Please note that there are known issues that we cannot fix on our part.
Editing Custom Fields on transition screens only works with the new transition experience enabled in Jira
Custom Fields Configuration Size
Jira has a limit of 32768 characters for custom field configurations. As a consequence, if you are using Editable To-Do List or Cascading Select List with a very large number of entries, you may, at some point, fail to add new entries.
If you are reaching this limit, we recommend trying to split the configuration into multiple custom fields, with smaller configurations.
