I get it. It's just I don't see any dev-put images in many big apps, besides a logo and a welcome screen. Updating them with dozens of megabytes doesn't feel okay. It seems like there's some bloat, or a vault management problems. Like in some seasonally updated games that put dupes to speed up load of a map or easily add new content on top of them instead of redownloading a brand new db. Some I followed shawed off tens of gigabytes by rearranging stuff.

Like, messengers. I don't get it how Viber wants more than 40+ mb per update having nothing but stickers, emoji already installed and probably don't change them much. Cheap wireless connection could allow them to ignore that for some reason and start to get heavier in order to offload some from their servers, for many images are localized. Is that probably what their updates are? Or they consequentially add beta patches after an approval, so you download a couple of them in a close succession after they get into public?
