I feel like my phone apps update constantly. In general, that’s a good thing, I assume. I figure they’re fixing bugs or whatever. However, I don’t run into issues very often, nowhere near the rate of updates, and nothing seems to change after the update.
Compare that to Steam games which update really infrequently and the changes are usually much more obvious.
I’m not normally a conspiracy guy but I have an old app that I swear they update (but not really) just so that people think it is active.
(No sources) but apps with no updates get removed from the stores. So yes , some updates are “nothing”.
