I am using the Android Messages app on a T-Mobile Galaxy S9+ and have been unable to turn on RCS messaging. This morning I received the material design update so I checked my settings to see if I could enable Chat features (as detailed here: and I didn't see the options listed. I then decided to uninstall and reinstall the app. Upon reinstall I noticed that I lost the material design interface update, but when I went into the settings of the app I saw the options for Chat features. However, they were grayed out ( I then made Android Messages my default messaging app, but then the options completely disappeared in settings ( Have any of you experienced this issue and know the solution? Thanks.

Edit: A restart brought back the new design but DIDN'T change the options listed.

I moved this from the Android Apps forum to the General Help forum since the former is intended for developers to promote their apps.
