Hello,
How much RAM does your Lenovo Tablet have? The reason I ask is that in
Changelog 95, Jack announced, 'S
tricter system requirements on Google Play: Phones with 1GB RAM or less and tablets with 2GB RAM or less can no longer install iGP Manager through Google Play." which means that some older devices are no longer able to update iGP Manager.
Jack writes in detail about why the recent update was mandatory in
this thread.
Sorry for any inconvenience this will cause.
