CC1352R: modification to simple_peripheral example not seen on app

Part Number:CC1352R

I have built and run the simple_peripheral example code on our custom board and am now trying to make modifications to it for my requirements.

I have changed some description strings (characteristics 1 & 2), change char2 to R/W, and removed characteristics 3-5. I have built and run this on the board (and some related changes to UART output are seen, so I know that the new code is running), however, my LightBlue and SensorTag apps are not showing the changes.

Actually, the first change I made, characteristic 1 description string, is showing up, but nothing since then (and that one may not have shown up immediately after I made the change).

What am I forgetting to do when I rebuild so that the apps see the changes?

Thanks!
