As an aside, from the latest release notes: Sandboxed Google Play compatibility layer: add toggle for granting Play services access to ICC auth in order to support RCS with carriers requiring it for RCS in Google Messages including T-Mobile (see RCS usage guide)
The best thing would be to switch to Signal (Molly) for texting.
If anything, iOS seems buggier and less reliable, but I know (and am related to) a lot of people who insist on using iMessage/RCS, and I can't be missing messages.
