Okay so no new announcements in the last year about the Samsung Messages app.
The FAQ associated with the post that kicked all of this off said:
Why can’t I use Samsung Messages?
The Samsung Messages app sends messages from your alternate number, which is a number that we use internally to route your calls and texts, and is different from your Republic Wireless number. We’re currently working with Samsung to integrate the Samsung Messages app with Republic Wireless as soon as possible."
The key term is “we are currently working with Samsung…”. Is that still happening? Did it stop because it wasn’t possible? Did it never happen and was just said that it was to keep people at bay until forgotten? If the original announcement said “it won’t work and it never will, so don’t bother us about it”, this would be a dead issue in my mind. But you said you were working with Samsung to integrate, I am expecting that there is some update that you have found a fix to the problem or you gave up and don’t intend to fix it.
If there is no intention to fix the issue, then update your republic wireless app to allow a checkbox to permanently disable the warning that shows up whenever Samsung Messages is selected and that we are doing so at our own risk. At that point it will become the users problem if they decide to continue to try to use it.
