I am subscribed to the Visual Voicemail version 126.96.36.199864 feature on my T-Mobile account on the Samsung Galaxy S8 running Oreo version 8.0.0. Most of the time, it fails to synchronize my messages to the app. I get a message that says it failed to synchronize messages and to make sure I am connected to the data network. This is happening whether WiFi is on or off and I'm never in an area where I am not well covered by the T-Mobile network. This is very annoying because I use my phone for business as well as personal calls and I need Visual Voicemail to work consistently!
I have uninstalled and reinstalled the app and cleared the data cache several times already.

Thanks for chiming in to let us know what's going on with Visual Voicemail. This is something our Engineers are already aware of and are working on fixing. At this time, we don't have an estimate of when it'll be back up and running as it should but we've collected enough examples to move forward with finding a solution. Once I receive an update, I'll be sure to update this thread.
