I think I may have an idea on how to fix bundles for mobile devices.  There is a feature for certain items, like the fishing rod, where a "use" button appears on the screen, perhaps the same mechanic is applied to the bundle, and when pressed, it opens a similar interface like the one a player encounters when opening a chest.  I'm unsure if this idea has already been considered, but if not, it may just help the bundles make it into an update in the near future.  Thank you for reading
