We have deleted most of the project related tags and ran the compact blob task as well. It released only small amount of memory, But still the blob storage occupied with huge storage. 1.9T. Is it safe to run Delete unused manifests and images task from UI and then compact task in 3.20.1 version. We saw in some threads that , we have some issues with this task .
