JQL no longer works

[Deleted user]

This query worked last week in Jira cloud.

project = ct AND ('Dev Team' = 'Visionet' or 'Dev Team' is Empty) AND (status was  'Code Review Comments' during ('2017/06/24','2017/06/24'))

Today I get this error

The DURING predicate must be supplied with exactly 2 date values

Any ideas

Mmh, has there been a cloud update since in not working anymore?

JQL should work and is working for me. Maybe try alternative date formats?

Valid formats include: 'yyyy/MM/dd HH:mm', 'yyyy-MM-dd HH:mm', 'yyyy/MM/dd', 'yyyy-MM-dd', or a period format e.g. '-5d', '4w 2d'.

Is

status was 'Code Review Comments' AFTER '2017/06/24' AND status WAS 'Code Review Comments' BEFORE '2017/06/24'

working?
