Hi,
There appears to have been an update or a push that has gone live over the last day or so that has changed us to having the Advanced lookup feature on. We don't seem to be able to turn this off via the admin center, so i assume this is just the new way moving forward. Unfortunately, we seem to be unable to select rows in the new UI, even system admin can't. Any advice on this, or has anyone seen this?

Update: Only occurs when the lookup field is selected from the Business process flow instead of the form.
