Why are some of the repeating options disabled?

Repeating options are disabled if the periods the product is published for would overlap. 

For example, if you have set the product to be published for 30 hours and you set it to repeat every day, then there would be a 6 hour overlap. To stop this from happening, the app disables the options that would create an overlapping problem!

Repeating options are also plan-dependent — repeating schedules are available on the Pro and Plus plans. If every repeating option is unavailable, check your plan on the Plan page.
