There may be hope with the words "hold pay." They may be seeking approval from a PM or the client for whatever reason. If they are not going to pay, typically the word "excluded" is used. You could try emailing the editor.
I had a $7 phone shop excluded yesterday without any notice. Did 3 in one day, 10/5. All sat in editing until 10/25 when I got a edit request on all 3. The editor is a over the top PITA. Never had so much back and forth on a phone shop.
Last night I was doing a query on my Oct shops and noticed 1 was excluded. Never got a notification, but did see the comments in the shop log.
I'm not going to loose sleep; even tho a phone shop, too much was required for $7 and honestly I'm happy to know the editor is now flying on her broom somewhere else.
