Xperia XZ1 G8342 on T-Mobile Group MMS

[Almendarez28]

Has anyone ran into this issue of not being able to reply to all users when sending MMS.  The stock android app doesn't have the MMS options in the advanced options.  I do not want to use a 3rd party app.  This is a very stupid and annoying issue that my previous Xperia Z5 did not have.

Model G8342

Android version 8.0.0

Build number 47.1.A.16.20
