Hi Tim,
How about ‌a feature that allows to download all updates regardless of kind, with just the press of one button?

Please understand that an AOPA publication is not law. It is at best a recommendation. If, as it appears, they are recommending pilots on a course of action that isn't actually required by law, you may wish to mention it to them.

I already explained above why we will not be implementing the prototyped "update all plates I have ever downloaded" button. That is not a good enough solution, and it is a solution to a problem which needs further defining.

In the case of the German VFR AIP product, those plates are updated on a well-known schedule every 28 days. We could email customers of that product at that time, which would be one solution.

It is possible we could a‌utomatically download plates for airfields along your route, but it has the following disadvantages:

1. SkyDemon eats a lot of bandwidth without being asked to, potentially in an expensive way on 3/4G
2. You are no longer aware when certain documents have been updated‌‌‌

Is there an option to automatically update if you're on wifi? Is there an option to have a warning that there are plates along your route that need to be updated, with a button to press to download all of them?

The latter in particular would certainly save a lot of time as it would avoid having to download entire AIPs or manually updating. e.g. I like to have all of UK installed, but really don't need *all* of Germany just because I pass through it on the way to Switzerland. The former could be something that appears at the top or bottom of the screen when planning, or potentially just a little red icon for plates and another for charts if you haven't updated those too.
