That's about where I am with this. I got started with GV back when carriers were charging $0.25/each to send or receive texts, and eventually paid Google $20 to port my old AT&T number into their system.
Then Google stopped developing the GV app and I switched from iOS to Android to get the Hangouts Dialer integration. With the Hangouts integration instead of a real GV app, they apparently threw away the spam reporting/filtering (on voice and text) that had been one of its greatest features.
Eventually I got fed up with the poor service. Third parties would refuse to accept my phone number, or would accept it but couldn't actually send me messages. Group MMS didn't work properly. As of late 2013, they "integrated" MMS support with T-Mobile and Sprint. When one of them tried to send you a picture, you'd receive it as an email attachment on your gmail account. MMS from AT&T and Verizon users, as far as I can tell, continue to disappear into the ether.
I have no idea how many missed social calls I had from people in college organizing social lives via group texts that I never got, and they never knew I didn't get because there was zero indication on either end that it wasn't delivered.
As far as I'm concerned, Google Voice is dead. Maybe this reincarnation lasts two years before management decides to refocus on Duo/Allo, or maybe it's six months. Maybe they throw it out and go all-in on a new Project-Fi based VOIP/messaging system. Either way, I'm staying out of it.
My number's been ported to T-Mobile on the $30 prepaid unlimited plan, and I switched back to an iPhone. Voicemail transcriptions work just as well as GV's did, and my text messages don't just vanish anymore. Everything's great.
