when trying to add collection, the oldest set is shown first followed by release order. i think it make more sense to have the newest set first instead of genetic apex first, as most of us would have collected most of the older sets and would be adding the new cards more than the older cards. promo would still be at the end of course.
They are sorted by card ID by default, which the app also does. We can add another sort filter though to sort it descending instead. I’ll make a ticket for someone to pick up.
