Collection Management in Azure Purview post 18th Aug '21 update

Hi All

With the changes to the Collection Management UI post the 18th Aug (2021) update. There has been some significant changes to how one manages your collection in Purview.

I have Collection Admin (as well as the other roles) on the root collection via a guest account to the organisation.

Previously we could

1) Move Collections between different hierarchies easily by changing a parent collection dropdown

2) Delete unused collections (trashcan)

Currently, we are unable to do any of the above? 

Can someone shed light on this please?

Many thanks
