A lot of reading there, I’ll be honest, I cherry picked a few bits.
It is for the most part not the best but I still use it for sending uncompressed images. If you use the Google messages SMS app it does offer a bit more. I still think they should get a bit of Kudos for trying but at the same time. The iterative death, rebrand and rebirth of Google messaging platforms has been terrible. Allo was the worst in my opinion.
