Hi folks, I cant install an updated version of an apk on my fire hd8 2018. Always comes up not installed. I did manage to Install a beta version but it's too buggy. Trying to save the apps data too. About a year ago i side loaded playstore etc. Seems that amazon os update messed things up. I've used the amazon fire toolbox etc to try to help. This tool won't update google framework either. Wallpaper won't stay on nova launcher either. I'm at a loss. Could anyone please help as I'm at my wits end. Really just need this one apk to work. Thanks
