I am a developer for www.sumppumpsusa.com and we are running into the same problem on our end.... To date, we have not seen a fix. We physically have to go into any one of our campaigns every other day and simply open one and save it and it triggers all campaigns to start running again.
If we get any fix or feedback on our end, we will be sure to let you know… Please do the same....
