For the past three months we've been having issues with group text messages where if we send out a group text message and someone in the group has T-Mobile, that person does not receive a group text message. Instead, they receive an individual text message from us and when they respond, it only comes back to us. This becomes an issue when say borrowers, agents, brokers, attorneys, etc. are all trying to get on the same page and the person using T-Mobile only sees the text from us and none of the other recipient's responses. It's been causing a lot of unnecessary confusion.
We've run into this numerous times now and are able to easily replicate the issue. We even replicated it when it first started happening with Customer Support during our first 3-hour call to them trying to fix this. We were told then that no one else has reported the issue, everything looks fine on their end, and for us to contact T-Mobile.
We're all setup with TCR as far as having a registered brand & campaign. We've also tried sending group texts from the windows app, website, the mobile app, all giving us the same outcome.
Has anyone else experienced this? More importantly, has anyone figured out a solution to it?
