I work at a major software/hardware company and am responsible for the customer support web site, so I totally understand the fine balance that is sometimes needed between performance and usability. I also know that customer/user feedback is very important, and for me, in my calling (again just one voice), I do have to look back and going from "the dawn of time" to 30-days was a significant leap.
My feedback is, for me, that's too much. My comment is that the pendulum went a bit too far to the performance side at the expense of usability, both in the case of the connection limit being set to an hour, and the history being cut to 30-days. Both changes at once created some confusion and a bit of frustration.

(And again, the connection limit being set to one hour is more than generous if all you're doing is checking for updates from a single point - most of the time the stake calendar only changes on a weekly basis so you would think setting the limit to once an hour would be just fine. However, it's the side effect of having multiple devices, getting them subscribed and not stepping on each other within the constraints of the hourly access limitation that's the problem, not the frequency of only checking for updates every hour. Most non-technical iPhone/iPad users are not going to understand how to setup their devices to make it work when you have to wait an hour to try again.)
I'm sure the development teams will weigh things carefully and I will work with the outcome. I truly appreciate the wonderful advances the Church has made by offering these tools and capabilities to us. I appreciate their fiscal conservatism as well, knowing that funding for projects like the calendar come from Church funds.
A big "Thanks!" to all those who work on these projects.
