SMS via 3rd party apps has and always will be buggy in some way, shape, or form, at least on Android. No clue why. Since the dawn of Android phones and after some 25-30 Android-specific phones owned in my life, I’ve yet to use a non stock SMS app that worked flawlessly all the time. Closest I’ve come, unfortunately, is Google Messages, and even that isn’t perfect.
My parents use Signal and are the most tech averse people I know, so it isn’t that hard. I converted all my friends to Signal. Switched wife to Signal.
SMS is maybe 3% of my usage these days and about 2% of that is just restaurant reservations or spam. There are two people I message via SMS like once a quarter and that’s it.
There are still…I dunno…probably DNS hops, IP, time’s of day, browser window size, browser user agent…
And if you access any page with any similar parameters on your phone or another household device on any site with FB tracking, it’s over.
It looks like in the last 7 days my phone has cutoff over 150,000 different tracking attempts and that’s just catchable ones and on my phone.
