Our upstream provider, Twilio, is currently experiencing an issue which is causing SMS delivery delays when sending messages to T-Mobile US devices via short codes. Ruvna delivers text messages through a short code, so text messages (including Health screenings and Announcements) may be delayed for users with T-Mobile devices. See https://status.twilio.com/incidents/8961zbmdjfxr
for more details.
We will resolve this incident once we have received confirmation the issue has been resolved from our upstream provider.
