Could you clarify it, please, and I'll update it on applying. Also, JFYI, you should update release notes for 22.07 release, not old release notes for 21.08. Don't worry about it now - I'll move and rephrase it on applying. Thanks, Andrew. ________________________________ ⚠ External Email: This email originated from outside of the organization.
