Inconsistent response while fetching Drive Changes using DeltaLink when a file checkout is discarded.

We are using DeltaLink to fetch the file changes in Document Library (Drive). We are getting file which was not actually changed in response. The file was checked out first and the checkout was discarded later hence, the file was not actually changed. Despite file not getting changed it was part of changes fetched using Delta Link.

Steps to reproduce:

  1. Get the Latest Delta Link for the drive with some files in it API:{driveId}/root/delta?token=latest
  2. Checkout a file in Drive manually or programmatically API:{driveId}/items/{itemId}/checkout
  3. Discard the checkout on the file manually or programmatically API: {SiteUrl}/_api/web/lists('{ListId}')/items(ListItemId)/file/undocheckout()
  4. Fetch the Drive changes using Delta Link fetched API:{driveId}/root/delta?token={DeltaToken}

Response received using delta link contains the file whose checkout was discarded, in other words the file was not actually changed and is still getting listed.

Expected behavior:
In case the checkout was discarded (the file was not actually changed) it should not be listed as part of response received using DeltaLink.

    Hi @Raj Poladia
    Per my test, I can get the same result as yours. The delta feed shows the latest state for each item, not each change. So when you check out and check in an item, it's state has been changed althought we didn't edit the content of the item. It will be listed as part of response. More details for reference
