It baffles me when I see new update on my play store and am always like is it a must to update?

though I update the apps I use and the ones I don't use I leave

what's the repercussion if one doesn't update an app that has new one? i.e the Facebook messenger I use it regularly but wanna know what happens if I don't update it? Will it crash,stop working or what?

Nothing happens dear, ignore them unless if necessary e.g whatsapp when it expires it stops opening, if u keep doing that have it in mind your mb wouldn't last long because some apps get a new version every 3days.

App update adds new features and fixes bugs, that the dev has been made aware of.
You don't have to update (read through the key notes on update, and see if the useful additions might benefit you).
I always update my apps as often has I get updates and also send bug reports to devs.

I get
I update the ones I need only and leave the rest
