Template to Device sync provides no feedback

[netniV]

Describe the bug

When syncing templates back to devices, no feedback is shown on screen once the "Continue" button is pressed. This means, you have no idea whether there is anything occurring and/or it is errored/locked up.

To Reproduce

Steps to reproduce the behavior:

1. Modify a template with a large number of items based upon it.

2. Sync changes and after clicking continue, see nothing back.

Expected behavior

Long running processes such as this should use a background process to execute with a status display returned that the front end can display whilst it is in progress.

Ideally, long term, all actions should operate this way to provide consistency.

Screenshots

Additional context

Any request made to the web should take no more than 5-10 seconds to complete. This prevents issues were users believe that they have either broken something or it's not running at all.

Yea, this whole thing should be backgrounded if it's going to take that long. I really don't know why it takes so long actually. I'll do a quick check. I suspect is re-running all queries, which should not be happening.

[TheWitness]

Okay, I've made an update that should make things very fast now, especially if there are no changes. As a feature request, we should allow this process to be backgrounded if you have thousands of devices and your are adding a few large data queries.

We shouldn’t close this as it was for the original background enhancement that is still outstanding.
