I recently purchased a ASUS ZenPad 8 running Android 7.0. I installed the VZ Messaging app on that tablet. The messaging feature works, however, I am not able to activate the integrated calling feature. I successfully used this feature on my old Samsung Galaxy Tab 4 with Android 5.0. I do have HD Voice activated on my mobile number. I spoke to a VZ customer representative today and was told that after April 2018 the integrated calling feature would no longer be able to be activated on new devices. I just want to verify that this information is accurate. If so, that should be included on the app description in the Google Play store. Thanks in advance for whatever assistance you can provide.
