Azyre dynamic groups with Direct reports for rule outdated

Question

Hello,

 

We have a lot of groups created with the Direct reports for "" rule in our organization. Recently, we noticed a lot of our groups being outdated and the workaround is to change to static and then back to dynamic with the same rule. We had this exact issue 6 months ago and Microsoft support suggested that it was related to the fact we were using '' instead of "" although the same workaround worked for ''. All groups were updated to "" and worked until recently when we started getting a lot of reports of groups being outdated.

Is this a backend issue with this rule or how can be investigated? There are no issues with it visible to us and we can't apply this workaround constantly.

 

Thanks
