I received a feedback from one of my users that map users that are not acknowledged with scanZone/scanNext's queue simply think manual scan would work right away. It would be great if there could be a better wording or colors suggesting that queue is long (red) or not. After all the main copy could be adjusted but the whole popup looks bad when copy is long.
Perfect solution would be to show if user's request was fulfilled or what's it's position in the queue or even an approx waiting time if possible.
