The listBlobs() method will only work for the same container again after the app's cache is cleared.

I am using the following code to list blobs (Kotlin)

` val storageAccount = CloudStorageAccount.parse(connectionString) val blobClient = storageAccount.createCloudBlobClient() val container = blobClient.getContainerReference(name) val blobs = container.listBlobs()

val blobNames: ArrayList = ArrayList() for (blob in blobs) { blobNames.add((blob as CloudBlockBlob).name) } `

Looks like the old requests are being cached in the com.microsoft.identity.http-cache folder in the app's cache directory. I need to delete the folder every time I run listBlobs().
