Package error fix didn't fix it still telling me to update the app but I don't have it
I'm sorry the package fix it basically the app renamed so it'll be recognized as new app. For some reason your phone isn't getting rid of the data it should. Androids and iPhone are very frustrating in that way. You'll have to figure out how to remove the hidden data but I'm not sure how to do that if the basic uninstall isn't working.
