Hi,

I'm near the breakdown ! Let me explain the situation :
I installed Nextgen World 9.18.27.736653 on 2 android phone (same apk source). One is Android 9 (A9 in the text), and the other Android 13 (A13 in the text).
It's exactly the same installation, same Pongo skin.
And to be sure that there is no difference, after APK installation, I made a copy of the folder of A13 to A9.

On A9, when I'm doing a change on a speedcam, this change dissapears on the next restart of iGo.
On A13, the change is always present after a restart.

When looking in privdocs/InappShop/Mount/speedcam, the file SpeedcamUpdates.spud is present on booth phone after iGo shutdown.
But on A9, SpeedcamUpdates.spud is reseted to size 0 at each iGo restart => user changes are deleted !

I cleared all data of the application (cache+user data) => no effect.

It's the first time I'm in face of such weird issue !!
