Deleting Video's From Cloud

I understand how to delete video's from the cloud one camera at a time but there must be a way to "select all" and have the system to delete all video's on the cloud at the same time from all of my cameras. Please give instruction on how to do this.  OPs, never mind I figured it out - { Open Ring Ap on phone, go to History, select devices, select all, filter devices, hit the pencil, hit delete all. Whalla all video's on all camera's were deleted in second and are not recoverable.
