Shared spatial anhors - Order of creation

Dear all

I'm saving a series of spatial anchors to the meta cloud and retreiving them via a group id and everything works well. The list of anchors I'm getting is however in random cronological order although always in the same order. Is there a way to get the last saved anchor?

I just need the latest, so I could clear all anchors when saving a new, but it is not possible to delete shared anchors on the cloud it seems, only persistent storage?

Thank you very much in advance!

Regards Thomas
