Schedule limit

Hi - I created 10 schedules. Some are form schedules and some are custom schedules (automatic emails). I realized that they suddenly stopped working. I believe that the issue is due the limit. Does the 31 schedule limit refers to number of scheduled that are set up? Or the number of actual occurrences within 24hrs?

If this 31 limit refers to the occurrences within 24hrs, can you please increase it to about 300 for my application?

We planned between 100 to 300 occurrences every night. They are equally divided in 5 events that occur between midnight and 7 am central time, so it should not impact your server.

Thanks
