I'm having trouble getting a subscription notification to fire without a manual update and a hard save. I've tried updating an on layout "helper" field via a schedule, but that does not seem to work either. Does anyone know how to get the subscription notification to fire other than a manual update?
One thing you can do is use a reminder, instead of a daily/weekly/monthly digest, that utilizes a field that calculates the current day of the week, or month (depending on the frequency you want to send the notification).
For example, I had a situation in which I needed to send weekly notifications to managers about overdue issues. Since most of the records wouldn't be hard-saved in that time, I set it up as a reminder notification but set one of my filter criteria to be: Helper: Current Day of Week Equals Tuesday. The helper field is a text field with the following formula: WEEKDAY(TODAY()). This way, the notification would send regardless of a hard save but only on the day of the week I specified in the filter criteria.
