I only ever used the lite version of FB Messenger. Shit was much better than the full version, especially without all the bloated "features" that I didn't use at best and being annoying/battery drains at worst. Was noticeably snappier on both my old and new phones. Fortunately most of my friends started using Discord and/or Signal with better features (and one less Meta app to have running).

I think that the idea of having smaller and less demanding versions of lots of apps is a good idea. As so many apps are just not optimized and bloated. Just being coded to rely on higher specs to make up for said lack of effort in cleaning up stuff. The ads on ads on ads being part of the issue as well. Which is only getting worse with the close buttons not loading unless shit has been however many seconds. Seems that the "hit box" for the close buttons is getting smaller and smaller to guaranty the ads are clicked on and then open another app or a browser. Though optimizations and better coding won't fix dirty underhanded grifts.
