I am trying to download the new update to my devices (Samsung Galaxy and Kindle Fire), and I keep receiving an error on my phone saying that the app "can't be installed on USB or SD card. Try again, and if problem continues, get help troubleshooting." I've already followed the troubleshooting steps.
If there was an issue that required me to unmount my SD card, I can only logically assume that I would receive this notification every time an app is newly downloaded or updated. I've already contacted the Google Play Store. I doubt there is anything they will tell me other than to contact the app admins. This has happened with one other game (Yu-Gi-Oh! Duel Links) and I've yet to be able to download it. So, here I am asking for help.
Also, I had uninstalled the app on my Fire, and now I'm stuck at a rookie level. I'm going to try to achieve level 4 and hope that I can have access to my cloud data. New update will not install on my Fire, too. I'll live if I can't play on my Fire, but I really want the version on my phone to work.
