Strange behavior of my ionic app

I’m developing a new app, i create build for ios and android working fine
When i make some chnages i increase version number that i see on setting page
The strange thing is this:
on device i run app, i go to setting page and see version 0.9.2 (latest)
i kill app and reopen
now version is one very old (0.8.9) and really my app is old because i see some feature missing
if i unistall app and reinstall is the same
iso & android with same behavior

Someone has found similar problem ?
Thanks
