It's worth noting that you're using an insecure end-of-life device and are missing a large number of High and Critical severity privacy/security patches including ones being exploited in the wild. Due to the device being end-of-life, you don't have firmware/driver patches, which are not being provided by your OS despite it continuing to support it. You're also missing important non-device-related OS patches due to /e/OS lagging behind and not shipping them properly.

You should really replace the device if you care at all about privacy and security. The 3 years of support for the Pixel 5 was not adequate for a significant portion of users. The past 2 generations of Pixels have 7 years of support from launch, which should be enough for most people.

/e/OS also doesn't ship proper signed production releases and doesn't keep the standard privacy/security model or features intact. It greatly reduces privacy and security compared to LineageOS which reduces them compared to the Android Open Source Project.

Purism's Librem 5 is definitely not the answer. It had dramatically worse hardware, firmware and software security than Pixels or iPhones from day one along with not providing high importance firmware updates to users. Presenting it as the answer to minor app compatibility issues also makes little sense since throwing out compatibility with most open source mobile apps and nearly all mainstream apps hardly resolves a subset of banking/financial apps and a tiny number of other apps banning using a non-stock OS.
