Verizon message + app won't update to latest version

I can't update the message+ app to the latest version. I have a galaxy s20+ and my fiancé has a galaxy s10 and his version of the app is 7.3.something and mine is 6.9.13. And it says my app is fully up to date. I don't use the message+ app bc it is so outdated and choppy but I like the version he has and would use it if I could get it updated to the same version.

Kam03, we know that new software is very exciting and that many enjoy making the changes to see new features. At this time. the 6.9.13 is the latest update for Messages + that is available for your device. Please know that when we do release updates for our applications, we do so in test batches,by make and model to ensure that if there are any issues we may address them along the way. We do look forward to providing that update to the S20+ in the future. LorenB_VZW If my response answered your question please click the _Correct Answer_ button under my response.
