Hello Nick,
Thank you for reporting this issue with Slam-It. We were able to reproduce and address the issue. It was adding the snipe, but just not displaying the "Snipe added" message. It didn't happen every time, so it was difficult to troubleshoot.
V2 is working, but not released in the browser app directories yet. I see we changed the location of it and didn't update the link properly. We'll have this resolved by the end of the week and post an update.
You should not see the issue any longer, but if so, let us know ASAP.
Thank you for writing in, and please let me know if you have any other questions.
