I've done a reset on my Tesco Hudl 2 and suddenly simpleplanes says " your device isn't compatible with this version ". However I'm still running the exact Android OS as before which is Android 5.1 lollipop. If this is fixable on your end or mine please let me know as this was my favorite go to game to let of some steam.
Cheers.
@SeraphimVault cheers for that it has worked now. 😁
