The details page of a card in the companion app used to list all printings. It now only lists the most recent printing. You can still access previous printings if you first filter by set, but this isn't useful if you're just trying to see all previous printings.

I think this bug coincides with the redesign of the Gatherer website, which turned the list of printings into a drop-down which appears at the top.

The drop down is cool, as is the "All prints" view (e.g. https://gatherer.wizards.com/prints/llanowar-elves/en-us), but it would be nice if the list of printings was still available in the companion app.
