Tommy, if I recall correctly, the app loader compares the internal version number between the current and new update. If the version is 230914, then you'll need an app update that has a version greater than that number. I'm checking this out and will follow up with you directly.
My guess is that you think your existing version number is 188.8.131.524, but Apple thinks your version number is 230914. I would try 231000 or 240000 or a high number like that. Let us know if that works.
[Note: I missed the 3-digit limitation in this reply. Have you tried using a marketing version such as 9.2.0?]
Thanks Nate and Bob. I agree that we need to increment higher than 230914. However, how do we do that within AEMM? We are very limited in the number of digits we can place in the version number manual override.
