I agree, 24 hours is not enough time since it is easy to miss due to any number of factors. That being said, many other bundles give no updates at all.
This is the first one I've personally missed, but it wont be the last. I decided to purchase it at the current discount this time.
A week seems more reasonable or even 72 hours versus 24 to accommodate work, life and time zone differences.
However, we all agreed to this when buying the bundle, so just see this as a vote for change if it is under consideration.
Oh, and great quality work again!
