: Older versions are often praised for being less "bloated." Users find them faster on aging hardware because they lack heavy features like high-end AR filters and complex animations.

Newer Messenger apps are notorious for pre-fetching videos and images, burning mobile data. Older versions (e.g., v190.0) had simpler caching mechanisms, resulting in lower data usage and extended battery life, especially on 4G networks.

If you are using an older device, here is a guide on how to safely handle old IPA versions. 1. Official Way: "Download Last Compatible Version"

This only works for versions you have an entitlement to (i.e., versions you’ve downloaded before). You cannot fetch a version from 2015 if you only started using Messenger in 2020.

This is the most critical factor. Old versions of apps lack the latest security patches. A vulnerability discovered and patched in version 300 might still be open in version 100. Using an outdated IPA could potentially expose your chat logs or account data to security risks.
